8.6 HIGH

Remote, low-complexity, unauthenticated SSRF; scope changes as the server pivots to internal systems (S:C) with high confidentiality via leaked responses, and no integrity or availability impact.

DescriptionCVE.org

LocalAI contains an unauthenticated server-side request forgery vulnerability in the POST /models/apply endpoint that allows attackers to fetch arbitrary internal URLs. The endpoint passes unsanitized gallery URL fields directly to gallery.GetGalleryConfigFromURLWithContext without proper validation, enabling attackers to force the server to issue HTTP GET requests to private and loopback ranges with partial response content leaked through error messages.

AnalysisAI

Server-side request forgery in LocalAI's POST /models/apply endpoint lets unauthenticated remote attackers coerce the server into issuing HTTP GET requests to arbitrary internal, private, and loopback addresses, with partial response bodies disclosed back through error messages. The flaw stems from passing attacker-controlled gallery URL fields into gallery.GetGalleryConfigFromURLWithContext without validation, giving attackers a network pivot from the internet into otherwise unreachable back-end services. …

Vulnerability AssessmentAI

Exploitation The prerequisite is network reachability to LocalAI's HTTP API with the model gallery/apply functionality accessible - specifically the POST /models/apply endpoint accepting a caller-supplied gallery URL field, which is passed to gallery.GetGalleryConfigFromURLWithContext without validation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals are largely consistent and point to genuine priority: the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) describes remote, low-complexity, unauthenticated exploitation with high confidentiality impact to both the vulnerable system (VC:H) and a subsequent system (SC:H), reflecting the internal-network reach an SSRF grants. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who can reach an internet-exposed LocalAI instance sends a single crafted POST /models/apply request whose gallery URL points at http://169.254.169.254/ or an internal admin service. The server fetches the URL on the attacker's behalf and returns partial response content inside its error message, letting the attacker enumerate internal hosts and harvest data such as cloud metadata credentials. …
Remediation Upstream fix available (PR/commit); released patched version not independently confirmed - apply the vendor fix in commit https://github.com/mudler/LocalAI/commit/f9b968e19d7cbc556d59dceb2e0e450b828a3fda by upgrading to a LocalAI build that includes it, then confirm the exact tagged release via the VulnCheck advisory (https://www.vulncheck.com/advisories/localai-server-side-request-forgery-via-post-models-apply) and issue #10665. … Detailed patch versions, workarounds, and compensating controls in full report.
