## Summary Zalo outbound photo URLs are validated through the SSRF guard. ## Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.4.21 - Fixed version: 2026.4.22 ## Impact The Zalo plugin could forward an attacker-controlled outbound photo URL to the Zalo Bot API without first applying OpenClaw's SSRF validation policy. ## Fix Zalo sendPhoto now parses and validates outbound photo URLs with the shared SSRF hostname policy before posting to Zalo, and media-reply paths route through the guarded outbound media helpers. ## Fix Commit(s) - a65eb1b864b7630c1242a82de9e5799b80583c3f ## Verification - The fix commit is contained in the public v2026.4.22 tag. - [email protected] is published on npm and the compiled package contains the fix. - Focused regression coverage for this path passed before publication. OpenClaw thanks @foodlook for reporting.
