CVE-2025-45766
📋 TL;DR
Poco v1.14.1-release contains weak encryption implementations that could allow attackers to decrypt sensitive data if applications don't properly configure encryption parameters. This affects applications using Poco's cryptography components with default or weak settings. The vulnerability is disputed as the library expects applications to set appropriate key lengths.
💻 Affected Systems
- Poco C++ Libraries
📦 What is this software?

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of encrypted data including passwords, session tokens, and sensitive information leading to authentication bypass and data theft.
Likely Case
Partial data exposure where attackers can decrypt some weakly encrypted information, potentially revealing sensitive configuration or user data.
If Mitigated
Minimal impact if applications properly configure strong encryption parameters and follow security best practices.
🎯 Exploit Status
Exploitation requires access to encrypted data and understanding of how the target application uses Poco's encryption. The GitHub gist shows technical details but not a complete exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified
Vendor Advisory: https://github.com/pocoproject/poco
Restart Required: No
Instructions:
1. Review Poco GitHub repository for updates. 2. If no official patch, ensure applications configure strong encryption parameters. 3. Consider updating to newer Poco versions if available.
🔧 Temporary Workarounds
Configure Strong Encryption Parameters
allEnsure applications using Poco set appropriate key lengths and encryption algorithms according to security best practices.
Application Code Review
allAudit application code to verify proper encryption configuration and usage of Poco cryptography components.
🧯 If You Can't Patch
- Implement additional encryption layer using properly configured cryptography libraries
- Restrict access to systems using vulnerable Poco versions and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check if application uses Poco v1.14.1-release and review encryption configuration in source code.
Check Version:
Check Poco version in build configuration or via library headers/version information.
Verify Fix Applied:
Verify applications configure strong encryption parameters (minimum 256-bit keys for symmetric encryption, proper RSA key sizes).
