Anki is a program for creating and reviewing flashcards. Prior to 25.09.3, Anki launches a local HTTP server to serve media files and web pages for parts of its interface, but requests from other origins were not sufficiently blocked. A malicious website could potentially trigger side-effecting requests to the local server, with severity varying by browser depending on Private Network Access protections. This issue is fixed in version 25.09.3.

- GHSA-869j-r97x-hx2gAnki's local HTTP server does not sufficiently validate requests2026-06-19ghsa · osvUS
## Summary Anki launches a local HTTP server to serve media files and web pages for parts of its interface. While the server has a CORS setup, requests from other origins were not blocked, allowing malicious websites to potentially trigger side-effecting requests. ## Browser impact The severity varies by browser because of Private Network Access (PNA), a newer spec that restricts web pages from making requests to localhost/local network addresses: Chrome/Chromium (including Edge, Brave): Largely protected, as Chrome has implemented PNA restrictions for several years and now puts local network access behind a permission prompt. Safari: Hasn't implemented PNA yet, though macOS has some OS-level protections. Firefox: Most vulnerable — hasn't implemented PNA yet, though it's reportedly planned for Firefox 151. ## Patches The issue was fixed as of Anki 25.09.3 ### References https://x.com/taviso/status/2051310678800253318
