CVE-2026-74886
CriticalCVSS 9.8Summary
openssl_encrypt versions before 1.4.0 contain a plugin sandbox bypass vulnerability where the PluginImportGuard blocks a different set of modules than the AST analyzer's DANGEROUS_MODULES set. Attackers can bypass AST analysis through string obfuscation or encoding to import unblocked dangerous modules like sys, shutil, multiprocessing, importlib, and pickle for arbitrary code execution.
Risk Assessment
The risk is that a malicious plugin can bypass security and execute arbitrary code, potentially leading to full system compromise.
Recommendation
Upgrade openssl_encrypt to version 1.4.0 or later, which synchronizes blocked module lists.
