{"id":"CURL-CVE-2016-8624","summary":"invalid URL parsing with '#'","details":"curl does not parse the authority component of the URL correctly when the host\nname part ends with a hash (`#`) character, and could instead be tricked into\nconnecting to a different host. This may have security implications if you for\nexample use a URL parser that follows the RFC to check for allowed domains\nbefore using curl to request them.\n\nPassing in `http://example.com#@evil.com/x.txt` would wrongly make curl send a\nrequest to evil.com while your browser would connect to example.com given the\nsame URL.\n\nThe problem exists for most protocol schemes.","aliases":["CVE-2016-8624"],"modified":"2026-04-25T20:38:53.439227Z","published":"2016-11-02T08:00:00Z","database_specific":{"www":"https://curl.se/docs/CVE-2016-8624.html","last_affected":"7.50.3","affects":"both","severity":"Medium","package":"curl","URL":"https://curl.se/docs/CVE-2016-8624.json","CWE":{"desc":"Encoding Error","id":"CWE-172"}},"affected":[{"ranges":[{"type":"SEMVER","events":[{"introduced":"6.0"},{"fixed":"7.51.0"}]},{"type":"GIT","repo":"https://github.com/curl/curl.git","events":[{"introduced":"ae1912cb0d494b48d514d937826c9fe83ec96c4d"},{"fixed":"3bb273db7e40ebc284cff45f3ce3f0475c8339c2"}]}],"versions":["7.50.3","7.50.2","7.50.1","7.50.0","7.49.1","7.49.0","7.48.0","7.47.1","7.47.0","7.46.0","7.45.0","7.44.0","7.43.0","7.42.1","7.42.0","7.41.0","7.40.0","7.39.0","7.38.0","7.37.1","7.37.0","7.36.0","7.35.0","7.34.0","7.33.0","7.32.0","7.31.0","7.30.0","7.29.0","7.28.1","7.28.0","7.27.0","7.26.0","7.25.0","7.24.0","7.23.1","7.23.0","7.22.0","7.21.7","7.21.6","7.21.5","7.21.4","7.21.3","7.21.2","7.21.1","7.21.0","7.20.1","7.20.0","7.19.7","7.19.6","7.19.5","7.19.4","7.19.3","7.19.2","7.19.1","7.19.0","7.18.2","7.18.1","7.18.0","7.17.1","7.17.0","7.16.4","7.16.3","7.16.2","7.16.1","7.16.0","7.15.5","7.15.4","7.15.3","7.15.2","7.15.1","7.15.0","7.14.1","7.14.0","7.13.2","7.13.1","7.13.0","7.12.3","7.12.2","7.12.1","7.12.0","7.11.2","7.11.1","7.11.0","7.10.8","7.10.7","7.10.6","7.10.5","7.10.4","7.10.3","7.10.2","7.10.1","7.10","7.9.8","7.9.7","7.9.6","7.9.5","7.9.4","7.9.3","7.9.2","7.9.1","7.9","7.8.1","7.8","7.7.3","7.7.2","7.7.1","7.7","7.6.1","7.6","7.5.2","7.5.1","7.5","7.4.2","7.4.1","7.4","7.3","7.2.1","7.2","7.1.1","7.1","6.5.2","6.5.1","6.5","6.4","6.3.1","6.3","6.2","6.1","6.0"],"database_specific":{"vanir_signatures":[{"source":"https://github.com/curl/curl.git/commit/3bb273db7e40ebc284cff45f3ce3f0475c8339c2","signature_version":"v1","deprecated":false,"signature_type":"Function","id":"CURL-CVE-2016-8624-21dabb6c","target":{"function":"parseurlandfillconn","file":"lib/url.c"},"digest":{"length":5303,"function_hash":"192314251346490770842994228226152588855"}},{"source":"https://github.com/curl/curl.git/commit/3bb273db7e40ebc284cff45f3ce3f0475c8339c2","signature_version":"v1","deprecated":false,"signature_type":"Line","id":"CURL-CVE-2016-8624-e5a561b6","target":{"file":"lib/url.c"},"digest":{"line_hashes":["167794969187132834335283326240322298758","2145756531567107512094677782452244826","323747900718285867694470904862247761631","72199516645593183555100184296947424249","103006003645429430163277688968008968563","175770485043618483373585366884754774864","129035539822800012486235675867282881458","185182450701402718154549178776349809532","70106979273968636074962406029356647628","56254145538747740195693065556051579026","168788442069164588453201833074777156037","170526936898557974342460186685632420595"],"threshold":0.9}}],"vanir_signatures_modified":"2026-04-25T20:38:53Z","source":"https://curl.se/docs/CURL-CVE-2016-8624.json"}}],"schema_version":"1.7.5","credits":[{"name":"Fernando Muñoz","type":"FINDER"},{"name":"Daniel Stenberg","type":"REMEDIATION_DEVELOPER"}]}
