CRITICAL 9.3EPSS 22.7%

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 22.7%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.

Description

Dify version 1.14.1 and prior contain a path traversal vulnerability that allows authenticated users to manipulate requests forwarded to the Plugin Daemon's internal REST API by exploiting insufficient URL path sanitization. Attackers can traverse out of their authorized tenant path using unencoded dot sequences in task identifiers or manipulated filename parameters to access internal endpoints such as debug interfaces, requiring only knowledge of the victim tenant's UUID. NOTE: Dify Cloud allows unauthenticated free self-registration, making account creation trivially accessible to any attacker.
