CVSS v3.1 |
| The issue was addressed with improved memory handling. This issue is fixed in Safari 26.2, iOS 18.7.3 and iPadOS 18.7.3, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, visionOS 26.2. Processing maliciously crafted web content may lead to an unexpected process crash. |
| In the Linux kernel, the following vulnerability has been resolved:
media: cxusb: no longer judge rbuf when the write fails
syzbot reported a uninit-value in cxusb_i2c_xfer. [1]
Only when the write operation of usb_bulk_msg() in dvb_usb_generic_rw()
succeeds and rlen is greater than 0, the read operation of usb_bulk_msg()
will be executed to read rlen bytes of data from the dvb device into the
rbuf.
In this case, although rlen is 1, the write operation failed which resulted
in the dvb read operation not being executed, and ultimately variable i was
not initialized.

| In the Linux kernel, the following vulnerability has been resolved:
jfs: validate AG parameters in dbMount() to prevent crashes
Validate db_agheight, db_agwidth, and db_agstart in dbMount to catch
corrupted metadata early and avoid undefined behavior in dbAllocAG.
Limits are derived from L2LPERCTL, LPERCTL/MAXAG, and CTLTREESIZE:
- agheight: 0 to L2LPERCTL/2 (0 to 5) ensures shift
(L2LPERCTL - 2*agheight) >= 0.
- agwidth: 1 to min(LPERCTL/MAXAG, 2^(L2LPERCTL - 2*agheight))
ensures agperlev >= 1.
- Ranges: 1-8 (agheight 0-3), 1-4 (agheight 4), 1 (agheight 5).
- LPERCTL/MAXAG = 1024/128 = 8 limits leaves per AG;
2^(10 - 2*agheight) prevents division to 0.
- agstart: 0 to CTLTREESIZE-1 - agwidth*(MAXAG-1) keeps ti within
stree (size 1365).
- Ranges: 0-1237 (agwidth 1), 0-348 (agwidth 8).

| In the Linux kernel, the following vulnerability has been resolved:
nfsd: Initialize ssc before laundromat_work to prevent NULL dereference
In nfs4_state_start_net(), laundromat_work may access nfsd_ssc through
nfs4_laundromat -> nfsd4_ssc_expire_umount. If nfsd_ssc isn't initialized,
this can cause NULL pointer dereference.
Normally the delayed start of laundromat_work allows sufficient time for
nfsd_ssc initialization to complete. However, when the kernel waits too
long for userspace responses (e.g. in nfs4_state_start_net ->
nfsd4_end_grace -> nfsd4_record_grace_done -> nfsd4_cld_grace_done ->
cld_pipe_upcall -> __cld_pipe_upcall -> wait_for_completion path), the
delayed work may start before nfsd_ssc initialization finishes.
Fix this by moving nfsd_ssc initialization before starting laundromat_work. |
| Multiple memory corruption issues were addressed with improved input validation. This issue is fixed in watchOS 26.2, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, visionOS 26.2, tvOS 26.2. A malicious HID device may cause an unexpected process crash. |
| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Don't leave consecutive consumed OOB skbs.
Jann Horn reported a use-after-free in unix_stream_read_generic().
The following sequences reproduce the issue:
$ python3
from socket import *
s1, s2 = socketpair(AF_UNIX, SOCK_STREAM)
s1.send(b'x', MSG_OOB)
s2.recv(1, MSG_OOB) # leave a consumed OOB skb
s1.send(b'y', MSG_OOB)
s2.recv(1, MSG_OOB) # leave a consumed OOB skb
s1.send(b'z', MSG_OOB)
s2.recv(1) # recv 'z' illegally
s2.recv(1, MSG_OOB) # access 'z' skb (use-after-free)
Even though a user reads OOB data, the skb holding the data stays on
the recv queue to mark the OOB boundary and break the next recv().
After the last send() in the scenario above, the sk2's recv queue has
2 leading consumed OOB skbs and 1 real OOB skb.
Then, the following happens during the next recv() without MSG_OOB
1. unix_stream_read_generic() peeks the first consumed OOB skb
2. manage_oob() returns the next consumed OOB skb
3. unix_stream_read_generic() fetches the next not-yet-consumed OOB skb
4. unix_stream_read_generic() reads and frees the OOB skb
, and the last recv(MSG_OOB) triggers KASAN splat.
The 3. above occurs because of the SO_PEEK_OFF code, which does not
expect unix_skb_len(skb) to be 0, but this is true for such consumed
OOB skbs.
while (skip >= unix_skb_len(skb)) {
skip -= unix_skb_len(skb);
skb = skb_peek_next(skb, &sk->sk_receive_queue);
...
}
In addition to this use-after-free, there is another issue that
ioctl(SIOCATMARK) does not function properly with consecutive consumed
OOB skbs.
So, nothing good comes out of such a situation.
Instead of complicating manage_oob(), ioctl() handling, and the next
ECONNRESET fix by introducing a loop for consecutive consumed OOB skbs,
let's not leave such consecutive OOB unnecessarily.
Now, while receiving an OOB skb in unix_stream_recv_urg(), if its
previous skb is a consumed OOB skb, it is freed.

| A local file inclusion (LFI) vulnerability in RiteCMS v3.1.0 allows attackers to read arbitrary files on the host via a directory traversal in the admin_language_file and default_page_language_file in the admin.php component |
| A Cross-Site Request Forgery (CSRF) in the page creation/editing function of RiteCMS v3.1.0 allows attackers to arbitrarily create pages via a crafted POST request. |
| Incorrect access control in the /templates/ component of RiteCMS v3.1.0 allows attackers to access sensitive files via directory traversal. |
| A reflected cross-site scripting (XSS) vulnerability in RiteCMS v3.1.0 allows attackers to execute arbitrary code in the context of a user's browser via a crafted payload. |
| RiteCMS v3.1.0 was discovered to use insecure encryption to store passwords. |
| RiteCMS v3.1.0 was discovered to contain an authenticated remote code execution (RCE) vulnerability via the parse_special_tags() function. |
| UliCMS 2023.1 contains a privilege escalation vulnerability that allows unauthenticated attackers to create administrative accounts through the UserController endpoint. Attackers can send a crafted POST request to /dist/admin/index.php with specific parameters to generate a new admin user with full system access. |
| ChurchCRM is an open-source church management system. Prior to version 5.21.0, a pre-authentication remote code execution vulnerability in ChurchCRM's setup wizard allows unauthenticated attackers to inject arbitrary PHP code during the initial installation process, leading to complete server compromise. The vulnerability exists in `setup/routes/setup.php` where user input from the setup form is directly concatenated into a PHP configuration template without any validation or sanitization. Any parameter in the setup form can be used to inject PHP code that gets written to `Include/Config.php`, which is then executed on every page load. This is more severe than typical authenticated RCE vulnerabilities because it requires no credentials and affects the installation process that administrators must complete. Version 5.21.0 patches the issue. |
| ChurchCRM is an open-source church management system. Prior to version 6.5.3, a SQL injection vulnerability exists in the `src/ListEvents.php` file. When filtering events by type, the `WhichType` POST parameter is not properly sanitized or type-casted before being used in multiple SQL queries. This allows any authenticated user to execute arbitrary SQL commands, including time-based blind SQL injection attacks. Any authenticated user, regardless of their privilege level, can execute arbitrary queries on the database. This could allow them to exfiltrate, modify, or delete any data in the database, including user credentials, financial data, and personal information, leading to a full compromise of the application's data. Version 6.5.3 fixes the issue. |
| ChurchCRM is an open-source church management system. Prior to version 6.5.3, a SQL injection vulnerability exists in the `src/UserEditor.php` file. When an administrator saves a user's configuration settings, the keys of the `type` POST parameter array are not properly sanitized or type-casted before being used in multiple SQL queries. This allows a malicious or compromised administrator account to execute arbitrary SQL commands, including time-based blind SQL injection attacks, to directly interact with the database. The vulnerability is located in `src/UserEditor.php` within the logic that handles saving user-specific configuration settings. The `type` parameter from the POST request is processed as an array. The code iterates through this array and uses `key($type)` to extract the array key, which is expected to be a numeric ID. This key is then assigned to the `$id` variable. The `$id` variable is subsequently concatenated directly into a `SELECT` and an `UPDATE` SQL query without any sanitization or validation, making it an injection vector. Although the vulnerability requires administrator privileges to exploit, it allows a malicious or compromised admin account to execute arbitrary SQL queries. This can be used to bypass any application-level logging or restrictions, directly manipulate the database, exfiltrate, modify, or delete all data (including other user credentials, financial records, and personal information), and could potentially lead to further system compromise, such as writing files to the server, depending on the database's configuration and user privileges. Version 6.5.3 patches the issue. |
| ChurchCRM is an open-source church management system. Prior to version 6.5.3, the allowRegistration, acceptKiosk, reloadKiosk, and identifyKiosk functions in the Kiosk Manager feature suffers from broken access control, allowing any authenticated user to allow and accept kiosk registrations, and perform other Kiosk Manager actions such as reload and identify. Version 6.5.3 fixes the issue. |
| Freedombox before 25.17.1 does not set proper permissions for the backups-data directory, allowing the reading of dump files of databases. |
| ChurchCRM is an open-source church management system. A privilege escalation vulnerability exists in ChurchCRM prior to version 6.5.3. An authenticated user with specific mid-level permissions ("Edit Records" and "Manage Properties and Classifications") can inject a persistent Cross-Site Scripting (XSS) payload into an administrator's profile. The payload executes when the administrator views their own profile page, allowing the attacker to hijack the administrator's session, perform administrative actions, and achieve a full account takeover. This vulnerability is a combination of two separate flaws: an Insecure Direct Object Reference (IDOR) that allows any user to view any other user's profile, and a Broken Access Control vulnerability that allows a user with general edit permissions to modify any other user's record properties. Version 6.5.3 fixes the issue. |
| ChurchCRM is an open-source church management system. A stored cross-site scripting (XSS) vulnerability exists in ChurchCRM versions 6.4.0 and prior that allows a low-privilege user with the “Manage Groups” permission to inject persistent JavaScript into group role names. The payload is saved in the database and executed whenever any user (including administrators) views a page that displays that role, such as GroupView.php or PersonView.php. This allows full session hijacking and account takeover. As of time of publication, no known patched versions are available. |
