CVE-2026-88756 — CWE-89 / CVSS v3 5.3
Attack vector: remote (network-reachable) / unauthenticated / no user interaction
Attack surface: POST /user/authenticate
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
SQL injection (CWE-89) has been reported. Attackers reach the vulnerable code path via POST /user/authenticate without authentication.
Check the vendor advisory for the affected versions. Attack surface: POST /user/authenticate.
Severity: Medium (CVSS 5.3/10). Risk of unauthorized operations or information disclosure.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual POST /user/authenticate requests with malformed payloads or SQL meta-characters. Audit SBOM/dependencies to find affected services.
