Vulnerability Data

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…

more

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.

Mitigating Controls (NIST 800-53 r5) AI

Explicit validation of path inputs stops .. sequences from ever being interpreted by the file system.

Access enforcement directly blocks unauthorized file reads/writes that result from unresolved .. sequences.

Information-flow rules can be configured to reject traversals that would move data outside an approved directory boundary.

Least privilege reduces the set of reachable files even when a traversal succeeds.

Secure-engineering principles require safe pathname construction and input neutralization before any file operation.

Secure SDLC practices directly require input validation and path sanitization that prevent relative traversal.

finds

Security testing in development catches path traversal via static/dynamic analysis, but does not itself implement the fix.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent relative path traversal.

prevents

Application security requirements explicitly call for controls against path traversal and other injection flaws.

prevents

Secure architecture principles include directory isolation and canonicalization, reducing but not eliminating traversal risk.

prevents

Secure coding standards require neutralizing path traversal sequences, directly addressing CWE-23.

mitigates

Information access restriction limits which files can be reached, mitigating impact but not preventing the traversal flaw.
