CVE-2026-74883 (GCVE-0-2026-74883)

Vulnerability from cvelistv5 – Published: 2026-08-17 11:04 – Updated: 2026-08-17 12:49

Title

openssl_encrypt before 1.4.0 Sandbox Bypass via pathlib and io

Summary

openssl_encrypt versions before 1.4.0 contain a sandbox bypass vulnerability where the plugin sandbox fails to restrict alternative file access methods like pathlib.Path and io.open. Attackers can import pathlib or io modules to read and write arbitrary files, completely bypassing the restricted_open file access controls.

Severity
