Detailsinfo

A vulnerability classified as critical has been found in PsychQuant LiveDocs up to 0.6.x. Affected is the function fetch_docs of the component Redirect. The manipulation of the argument URL with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

LiveDocs is a primary-source-first documentation for AI agents. Prior to version 0.7.0, fetch_docs and introspect (kinds openapi/graphql, and resolve_source's docs_url) pass a client-supplied URL straight to URLSession with no scheme or host allowlist, and redirects are followed unconditionally. A prompt-injection payload embedded in fetched documentation can steer the model to call fetch_docs against internal or metadata endpoints and stream the response back into the conversation. This issue has been patched in version 0.7.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-63651 since 07/17/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1055 by the MITRE ATT&CK project.

Upgrading to version 0.7.0 eliminates this vulnerability.
