CVE-2026-82335

Status: AnalyzedCritical (9.8)—

IBM Guardium Data Protection 12.0, 12.1, 12.2 is vulnerable to a heap-based buffer overflow in the MongoDB protocol parser. A remote attacker could send a specially crafted MongoDB SCRAM username containing an excessive length and cause memory corruption, potentially resulting in denial of service or arbitrary code execution.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vector CVSS AV:N/AC:H/PR:N/UI:N indica explotación remota sin autenticación (T1190). Heap overflow en parser MongoDB permite ejecución de código (T1059) o DoS (T1499.004).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
