In gatts_process_read_by_type_req of gatt_sr.cc, there is a possible out of bounds write due to a logic error in the code. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.

An issue in System.Linq.Dynamic.Core Latest version v.1.4.6 allows remote access to properties on reflection types and static properties/fields.

An issue in RAR Extractor – Unarchiver Free and Pro v.6.4.0 allows local attackers to inject arbitrary code potentially leading to remote control and unauthorized access to sensitive user data via the exploit_combined.dylib component on MacOS.

An improper verification of cryptographic signature vulnerability was identified in GitHub Enterprise Server that allowed signature spoofing for unauthorized internal users. Instances not utilizing SAML single sign-on or where the attacker is not already an existing user were not impacted. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.12.14, 3.13.10, 3.14.7, 3.15.2, and 3.16.0. This vulnerability was reported via the GitHub Bug Bounty program.

The mqlink.elf is service component in Ruijie RG-EW300N with firmware ReyeeOS 1.300.1422 is vulnerable to Remote Code Execution via a modified MQTT broker message.

Homarr before v0.14.0 was discovered to contain a stored cross-site scripting (XSS) vulnerability via the Notebook widget.

Mjolnir is a moderation tool for Matrix. Mjolnir v1.9.0 responds to management commands from any room the bot is member of. This can allow users who aren't operators of the bot to use the bot's functions, including server administration components if enabled. Version 1.9.1 reverts the feature that introduced the bug, and version 1.9.2 reintroduces the feature safely. Downgrading to version 1.8.3 is recommended if upgrading to 1.9.1 or higher isn't possible.

YesWiki is a wiki system written in PHP. In versions up to and including 4.4.5, it is possible for any authenticated user, through the use of the filemanager to delete any file owned by the user running the FastCGI Process Manager (FPM) on the host without any limitation on the filesystem's scope. This vulnerability allows any authenticated user to arbitrarily remove content from the Wiki resulting in partial loss of data and defacement/deterioration of the website. In the context of a container installation of YesWiki without any modification, the `yeswiki` files (for example .php) are not owned by the same user (root) as the one running the FPM process (www-data). However in a standard installation, www-data may also be the owner of the PHP files, allowing a malicious user to completely cut the access to the wiki by deleting all important PHP files (like index.php or core files of YesWiki). Version 4.5.0 contains a patch for this issue.
