CVE-2026-74883: Protection Mechanism Failure in jahlives openssl_encrypt
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.
AI Analysis
Technical Summary
CVE-2026-74883 is a vulnerability in the jahlives openssl_encrypt plugin prior to version 1.4.0. The sandbox mechanism intended to restrict file access fails to block alternative Python file access methods, specifically via the pathlib and io modules. Attackers can exploit this flaw to import these modules and perform arbitrary file read and write operations, bypassing the restricted_open controls designed to limit file system access.
Potential Impact
An attacker can bypass sandbox restrictions to read and write arbitrary files on the affected system. This can lead to unauthorized data disclosure, data manipulation, or potential further compromise depending on the files accessed or modified.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Users should monitor the vendor's advisory for updates and avoid using vulnerable versions if possible.
