CVE-2026-54242 Statamic: Server-Side Request Forgery via Glide (DNS rebinding)

Statamic is a Laravel and Git powered content management system CMS. Prior to 5.73.24 and 6.20.1, the Glide image proxy's URL validation in src/Imaging/RemoteUrlValidator.php and src/Imaging/GuzzleAdapter.php could be bypassed using DNS rebinding. The remote hostname was validated as publicly...

CVE-2026-62212 OpenClaw < 2026.5.28 Authentication Bypass via safeFetch

OpenClaw before 2026.5.28 contains a race condition in the MS Teams safeFetch DNS rebinding check. When the affected feature is enabled and reachable, a lower-trust caller or configured input path could win a timing window between the DNS validation check and use, allowing actions that should hav...

CVE-2026-61430

PraisonAI before 1.6.78 contains a server-side request forgery (SSRF) vulnerability in the web_crawl tool. The issue arises because hostnames are validated at check time but re-resolved at connect time without IP pinning, enabling DNS rebinding to bypass SSRF protections and read internal HTTP re...
