CVE-2025-50738: The Memos application, up to version v0.24.3, allows for the embedding of markdown images with arbitrary URLs.

CriticalCVSS 9.8 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Plan (action score 40/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.4% (FIRST EPSS); higher than 84.4% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: github.com/usememos/memos (Go) 0.24.4; govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20250814T182633-150000.1.98.1; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250811T192933-1.1.

Add it to your regular patch cycle. Upgrade to github.com/usememos/memos (Go) 0.24.4; govulncheck-vulndb (openSUSE:Leap 15.6) 0.0.20250814T182633-150000.1.98.1; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250811T192933-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The Memos application, up to version v0.24.3, allows for the embedding of markdown images with arbitrary URLs. When a user views a memo containing such an image, their browser automatically fetches the image URL without explicit user consent or interaction beyond viewing the memo. This can be exploited by an attacker to disclose the viewing user's IP address, browser User-Agent string, and potentially other request-specific information to the attacker-controlled server, leading to information disclosure and user tracking.
