CVE-2026-5656

Profile import path traversal in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service and possible code execution

View on NVD

Analysis

Wireshark versions 4.4.x and 4.6.x are vulnerable to a path traversal flaw when importing profiles. A crafted profile file can lead to a denial of service or potential code execution on the user's machine, making it critical to update to a patched version before importing shared configurations.

How to read this card

Actively exploited

KEV (Known Exploited Vulnerabilities) is CISA's catalog of CVEs confirmed as actively exploited in the real world. If a CVE is on KEV, someone is already using it in attacks.

CVSS 10.0

CVSS 10.0 — máxima severidad teórica. Explotable de forma remota, sin privilegios, con impacto total. Aún no confirmada como explotada en el mundo real, pero parchea ya.
