MEDIUM 5.9EPSS 0.18%

Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

OpenClaw before 2026.4.8 treats shared reply MEDIA paths as trusted, allowing crafted references to trigger cross-channel local file exfiltration. Attackers can exploit this by crafting malicious shared reply MEDIA references to cause another channel to read local file paths as trusted generated media.
