CVE-2026-10860: MISP CRUDComponent delete validation bypass via operator precedence error
- Severity: medium (CVSS 6.5 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-06-04 · updated 2026-07-22
- Weakness: CWE-863
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.
