PraisonAI Allowlist Bypass via Find Command Actions

Executive Summary

CVE-2026-61434 is a security vulnerability in PraisonAI versions before 4.6.78 that allows attackers to bypass the allowlist restrictions on shell command execution.

The vulnerability exploits the built-in actions of the `find` command, specifically `-exec`, `-execdir`, and `-delete`, which can execute commands without triggering shell metacharacter filters.

Because `find` is included in the safe command allowlist, attackers can craft commands using these actions to execute restricted commands, read blocked files, delete files, or run binaries that are not on the allowlist.

Impact Analysis

This vulnerability can have a significant impact on the confidentiality, integrity, and availability of your system.

• Attackers can execute arbitrary commands that are supposed to be restricted.
• They can read files that are blocked or sensitive.
• They can delete important files, potentially causing data loss or service disruption.
• They can execute binaries that are not on the allowlist, potentially leading to further compromise.

Overall, this can lead to unauthorized access, data breaches, and system instability.

Detection Guidance

This vulnerability involves the use of the `find` command's built-in `-exec`, `-execdir`, and `-delete` actions to bypass allowlist restrictions. To detect exploitation attempts, monitoring for unusual or unauthorized usage of these `find` command flags is recommended.

• Check for `find` commands using `-exec`, `-execdir`, or `-delete` in shell history or running processes.
• Use commands like `ps aux | grep 'find .* -exec'` to identify running processes that might be exploiting this.
• Search system logs or audit logs for invocations of `find` with these flags, for example: `grep -r --include='*.log' 'find .* -exec' /var/log/`.
• Implement file integrity monitoring to detect unexpected file deletions or modifications that could result from exploitation.

Mitigation Strategies

Immediate mitigation steps include removing the `find` command from the allowlist used by PraisonAI or enhancing input validation to reject dangerous `find` flags such as `-exec`, `-execdir`, and `-delete`.

• Upgrade PraisonAI to version 4.6.78 or later where this vulnerability is fixed.
• If upgrading is not immediately possible, configure the system or application to block or monitor usage of `find` commands with the risky flags.
• Review and tighten shell command execution policies to prevent execution of non-allowlisted binaries.

Compliance Impact

The vulnerability in PraisonAI allows attackers to execute arbitrary commands, read or delete files, and bypass path restrictions, which can lead to unauthorized access and manipulation of sensitive data.

Such unauthorized access and potential data breaches could negatively impact compliance with data protection standards and regulations like GDPR and HIPAA, which require strict controls over data confidentiality, integrity, and availability.

However, the provided information does not explicitly discuss the direct impact on compliance with these standards.
