GitHub AdvisoriesGHSA-2hh7-c75g-qj2r
OpenClaw validates Zalo outbound photo URLs through the SSRF guard
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.
