Zoraxy: Authenticated Path Traversal in Config Import leads to RCE

Zoraxy is a general purpose HTTP reverse proxy and forwarding tool. Prior to version 3.3.2, an authenticated path traversal vulnerability in the configuration import endpoint allows an authenticated user to write arbitrary files outside the config directory, which can lead to RCE by creating a plugin. Version 3.3.2 patches the issue.

Lychee has SSRF bypass via incomplete IP validation in Photo::fromUrl — loopback and link-local IPs not blocked

Lychee is a free, open-source photo-management tool. The patch introduced for GHSA-cpgw-wgf3-xc6v (SSRF via `Photo::fromUrl`) contains an incomplete IP validation check that fails to block loopback addresses and link-local addresses. Prior to version 7.5.1, an authenticated user can still reach internal services using direct IP addresses, bypassing all four protection configuration settings even when they are set to their secure defaults. Version 7.5.1 contains a fix for the issue.

cryptodev-linux <= 1.14 get_userbuf Use After Free LPE

cryptodev-linux version 1.14 and prior contain a page reference handling flaw in the get_userbuf function of the /dev/crypto device driver that allows local users to trigger use-after-free conditions. Attackers with access to the /dev/crypto interface can repeatedly decrement reference counts of controlled pages to achieve local privilege escalation.
