What is CVE-2026-10860?
CVE-2026-10860 is a high-severity missing authorization vulnerability in Misp-Project Misp, published on 4 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
A logic error in the MISP CRUD component delete handler allowed validation failures to be bypassed when requests used the HTTP DELETE method. Due to missing parentheses in the delete condition, the expression was evaluated as ($validationError === null && POST) || DELETE, meaning a DELETE request could proceed even when the delete validation callback had rejected the operation. An authenticated attacker with access to an affected delete endpoint could abuse this flaw to delete records that should have been protected by application-level validation or authorization checks.
