CVE-2026-74883
HighCVSS 8.8Summary
openssl_encrypt before version 1.4.0 contains 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.
Risk Assessment
The risk includes full compromise of data integrity and confidentiality, as attackers can gain unrestricted access to the file system.
Recommendation
It is recommended to upgrade openssl_encrypt to version 1.4.0 or later, which includes a fix that strengthens the sandbox and blocks alternative file access methods.
