Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.","published":"2017-08-11T21:29:01.000Z","lastModified":"2026-06-17T01:28:57.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":["apache/subversion"],"epss":{"score":0.18892,"percentile":0.97279,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.17798,"percentile":0.97097},{"date":"2026-09-22","score":0.18892,"percentile":0.97167}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 18.9%, higher than 97% of all known CVEs.
