DescriptionCVE.org

Snipe-IT before 8.6.0 contains an authorization bypass (insecure direct object reference) in the asset checkout-request cancellation endpoint. The cancel_by_admin and requestingUser values are read from user-controlled URL path segments and used without a server-side authorization check, so any authenticated, low-privileged user can supply a non-empty cancel_by_admin value to bypass the request-ownership check and cancel another user's pending checkout request. Because asset and user identifiers are sequential integers, an attacker can enumerate them to cancel every pending checkout request, disrupting the asset-request workflow. This is fixed in Snipe-IT 8.6.0.

AnalysisAI

Authorization bypass in Snipe-IT before 8.6.0 allows any authenticated low-privileged user to cancel other users' pending asset checkout requests by supplying arbitrary values in URL path segments. The checkout-request cancellation endpoint reads cancel_by_admin and requestingUser directly from user-controlled URL segments without server-side ownership validation, enabling any logged-in user to bypass request-ownership checks. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid authenticated session with at least low-privileged user access to the Snipe-IT web application - unauthenticated exploitation is not possible (CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.3 (Medium) correctly reflects network accessibility (AV:N), low complexity (AC:L), no attack requirements (AT:N), low-privilege authentication (PR:L), and no user interaction (UI:N), with limited integrity and availability impact on the vulnerable system and no confidentiality exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Snipe-IT user with minimal privileges sends crafted HTTP requests to the checkout-request cancellation endpoint, inserting a non-empty `cancel_by_admin` value and iterating sequential integer values for asset and user IDs in the URL path. With no server-side ownership validation in place, each request successfully cancels a target user's pending checkout request without error or privilege check. …
Remediation Vendor-released patch: Snipe-IT 8.6.0. … Detailed patch versions, workarounds, and compensating controls in full report.
