The feed viewer: this site, the records, and your own feeds

Every feed here is read by your browser, directly from its publisher, and what you have read in each is kept with the rest of your desk: the next time you come, a feed shows you only what is new or changed. This site's own feeds are first; then the outside sources a browser is allowed to read (the CVE records, NVD, OSV, CISA's catalog of exploited flaws, GitHub, Wikipedia, Hacker News, Mastodon); then the ones that do not allow it, and why. Add any feed you like below the list.

What the viewer does with a feed

• Your browser fetches it, with no cookies and no referrer, from the publisher; nothing goes through this site or anyone else.
• Only https feeds, and never an address on your own network. At most 2 MB is read (5 MB for a records API), within 15 seconds.
• A feed is shown as text: titles and summaries are parsed by the browser and only their words kept, so nothing in a feed can run on this page. Links open in a new tab, only when they are web links.
• A publisher that does not allow other sites' pages to read its feed (no CORS header) cannot be read here. The viewer says so rather than routing it through a third party, which would see what you read. The feeds the viewer at /reader/ offers on 2026-10-22.
