RestrictedPython guard hooks can be shadowed via positional-only arguments

ImpactRestrictedPython rewrites sensitive operations to go through guard hooks. Attribute access becomes getattrobj, name, item access becomes getitemobj, key, writes go through write, and print goes through print. The embedding application supplies these hooks to enforce its policy.Argument-name...

PraisonAI: [Path Traversal] agent tools escape the configured workspace via symlinks

SummaryPraisonAI's praisonai.code tool wrappers exported as CODETOOLS for agents expose a workspace setting that the module itself treats as a path-traversal security boundary — readfile, writefile, applydiff, and searchreplace explicitly call ispathwithindirectory and return "… is outside the...

CVE-2026-84042

A flaw was found in crun. When crun is built with libkrun and a container is started rootful with passt networking krun.usepasst, crun can execute attacker-controlled payload from the container image with host root privileges. The issue is a regression in crun 1.29. It affects crun = 1.29...

CVE-2026-88265

A flaw was found in crun. After pivotroot, reopening /dev/null for stdio can follow a symlink and attach a host file to container stdio, then change that file's ownership. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh /dev are not exposed. No fixed relea...

USN-8741-1: Flatpak vulnerabilities

It was discovered that Flatpak did not properly validate paths in sandbox-expose options. A malicious or compromised Flatpak app could use app-controlled symlinks to access arbitrary host files and gain code execution in the host context. This issue was addressed in Ubuntu Ubuntu 20.04 LTS, Ubunt...

CVE-2026-88264

crun , a container runtime, is affected by a /dev/console symlink-follow flaw (CVE-2026-88264). When the container configuration does not assign a dedicated mount to /dev, terminal setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-mount fall...
