Improper access control in Weaver prior to SMR Aug-2026 Release 1 allows local attackers to cause device inoperability.

In geniezone, there is a possible escalation of privilege due to a missing permission check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10900493; Issue ID: MSV-6765.

In display, there is a possible memory corruption due to use after free. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11019722; Issue ID: MSV-7759.

The PPWP: Password Protect Pages, Posts & Full or Partial Content plugin for WordPress is vulnerable to unauthorized access of data due to a improper capability check on the can_access function in all versions up to, and including, 1.9.15. This makes it possible for authenticated attackers, with Contributor-level access and above, to retrieve a master-password and access any password-protected content.

linuxfabrik-lib provides Python modules for database access, caching, shell execution, and API integrations, and Linuxfabrik Monitoring Plugins uses its shared testing helper across check plugins. Prior to linuxfabrik-lib 6.1.0 and Linuxfabrik Monitoring Plugins 7.0.0, lib.lftest.test() treated the first or second element of a --test CSV argument as a filesystem path and returned the file contents as simulated standard output or standard error without path confinement. The hidden but production-

Subscriber Insecure Direct Object References (IDOR) in Modal Survey <= 2.0.2.2.3 versions.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in David Artiss Draft List simple-draft-list allows Stored XSS. This issue affects Draft List: from n/a through 2.6.4.

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted HEIF or AVIF file containing a clean aperture box can reduce an image dimension to zero and crash or corrupt tiling results when heif_image_handle_get_image_tiling(handle, 1, &tiling) is called. ImageItem::get_heif_image_tiling() returns already transformed dimensions, and process_image_transformations_on_tiling() applies the clean aperture transformation again. The second application passes zero to Box_

Cross-Site Request Forgery (CSRF) vulnerability in kareemsultan Social Links social-links allows Cross Site Request Forgery. This issue affects Social Links: from n/a through 1.0.11.

### Summary The `graph_descr.<graphtype>` family of settings is echoed verbatim without `htmlspecialchars()` in `includes/html/pages/graphs.inc.php:194`. Any admin can store a malicious HTML payload that executes in every authenticated user's browser viewing that graph type. ### CVSS `CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N` — **4.8 Medium** ### Details ```php // graphs.inc.php:194 echo LibrenmsConfig::get('graph_descr.' . $vars['type']); ``` ### PoC ``` PUT /settings/graph_descr.device_

# Remote Code Execution via AboutController in LibreNMS ## Summary A Remote Code Execution (RCE) vulnerability exists in LibreNMS 26.3.1 through the AboutController. An authenticated administrator can manipulate the `snmpget` configuration parameter to execute arbitrary system commands. When the `/about` endpoint is accessed, the application executes the configured binary path via `shell_exec()` without proper validation. This vulnerability leads to complete server compromise, allowing attacke

Mattermost versions 11.8.x <= 11.8.2, 11.7.x <= 11.7.6, 10.11.x <= 10.11.21 fail to restrict channel member role assignment to channel-scoped roles which allows a channel administrator to gain additional channel permissions via the channel member roles API.. Mattermost Advisory ID: MMSA-2026-00697

Mattermost versions 11.7.x <= 11.7.6, 10.11.x <= 10.11.21, 11.8.x <= 11.8.3 fail to validate that users have read access to a channel before linking a board to it, which allows an authenticated attacker to discover the membership of private channels on the same team via creating, patching, importing, or bulk-creating boards with an arbitrary channelId. Mattermost Advisory ID: MMSA-2026-00674

### Impact If the replication protocol is enabled by using the ``primary`` (or deprecated ``master``) role for a server instance, then the ``+changelog`` URL route can be used to read the complete database content including password hashes, and the ids and salts of tokens from ``devpi-tokens`` by using a trivially modified GET request. The leaked hashes use the ``argon2`` algorithm, so they are not immediately at risk by brute-force methods, but dictionary attacks are feasible. If a database l
