Prior to 1.5.128, the execute_command function in shell_tools.py calls os.path.expandvars() on every command argument at line 64, manually re-implementing shell-level environment variable expansion despite using shell=False (line 88) for security. This allows exfiltration of secrets stored in environment variables (database credentials, API keys, cloud access keys). The approval system displays the unexpanded $VAR references to human reviewers, creating a deceptive approval where the displayed command differs from what actually executes. This vulnerability is fixed in 1.5.128.","published":"2026-04-09T22:16:36.350","modified":"2026-06-17T10:44:46.847","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},"epss":{"score":0.00273,"percentile":0.19336,"asOf":"2026-08-06"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"EXPLOIT","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-v8g7-9q6v-p3x8"},{"type":"EXPLOIT","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-v8g7-9q6v-p3x8"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-06-17T10:44:46.847"}}
