CVE-2026-56074: PraisonAI - Tool Approval Cache Bypass via Coarse-Grained Caching

• Severity: medium (CVSS 5.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-18 · updated 2026-10-26
• Weakness: CWE-863

Description

PraisonAI before 1.5.128 caches tool approval decisions by tool name only, not by invocation arguments, allowing subsequent execute_command calls to bypass approval prompts. Attackers can exploit this by obtaining initial approval for a benign command, then silently exfiltrate API keys and credentials via subsequent shell commands without user consent.

Affected products

• PraisonAI: before 1.5.128 — fixed in 1.5.128

How to fix

Upgrade to a fixed version: PraisonAI 1.5.128. Check the vendor advisory for mitigations.
