CVE-2025-50738

44
FAUCET Score

CVE-2025-50738 is a critical information disclosure vulnerability affecting Memos application versions up to v0.24.3. It allows attackers to embed malicious markdown images with arbitrary URLs, which, when viewed, automatically fetch content from attacker-controlled servers. This enables the disclosure of user IP addresses, User-Agent strings, and other request-specific information. The vulnerability has a CVSS score of 9.8 (Critical) due to its network-based attack vector, low complexity, and high impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation or Metasploit modules, a Nuclei template for a related Stored Cross-Site Scripting vulnerability exists, and community discussion and media coverage are currently minimal.
