Published: 27 February 2025
Summary
CVE-2025-22952 is a critical-severity SSRF (CWE-918) vulnerability in Usememos Memos. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 3.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
elestio memos v0.23.0 is vulnerable to server-side request forgery because of insufficient validation of user-supplied URLs. The affected component is the open-source memos application hosted at elest.io and maintained in the usememos/memos GitHub repository, and the flaw is tracked as CWE-918 with a CVSS 3.1 score of 9.8.
An unauthenticated remote attacker can supply crafted URLs to trigger SSRF requests, enabling arbitrary interaction with internal or external resources and resulting in high impact to confidentiality, integrity, and availability. The published EPSS score stands at 0.2794 with a recorded peak of 0.3498.
References point to the project repository, an open issue, and a pull request that address the flaw, though no explicit mitigation guidance is provided in the available sources.
