CVE-2026-74899: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') in jahlives openssl_encrypt
A critical sandbox escape vulnerability exists in jahlives openssl_encrypt versions before 1.4.0. The flaw allows attackers to bypass restrictions in the IsolatedPluginExecutor by exposing Python type objects within restricted exec() builtins. This enables traversal of the Python class hierarchy to execute arbitrary operating system commands.
AI Analysis
Technical Summary
CVE-2026-74899 affects jahlives openssl_encrypt prior to version 1.4.0. The vulnerability arises from improper neutralization of directives in dynamically evaluated code, specifically in the IsolatedPluginExecutor component. Attackers can exploit this by accessing Python type objects exposed in restricted exec() builtins and traversing the class hierarchy via __class__.__mro__.__subclasses__(), ultimately leading to arbitrary OS command execution. This represents an 'eval injection' style sandbox escape.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary operating system commands on the affected system, potentially leading to full system compromise. The vulnerability has a CVSS 4.0 score of 9.3 (critical), indicating high impact with no required privileges or user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented at this time.
