Flarum is affected by a vulnerability that allows an attacker to conduct a Blind Server-Side Request Forgery (SSRF) attack or disclose any file on the server, even with a basic user account on any Flarum forum. By uploading a file containing a URL and spoofing the MIME type, an attacker can manipulate the application to execute unintended actions. The vulnerability is due to the behavior of the `intervention/image` package, which attempts to interpret the supplied file contents as a URL, which then fetches its contents. This allows an attacker to exploit the vulnerability to perform SSRF attacks, disclose local file contents, or conduct a blind oracle attack. This has been patched in Flarum version 1.8.0. Users are advised to upgrade. Users unable to upgrade may disable PHP's `allow_url_fopen` which will prevent the fetching of external files via URLs as a temporary workaround for the SSRF aspect of the vulnerability."}],"source":{"advisory":"GHSA-67c6-q4j4-hccg","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T18:24:54.634Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/flarum/framework/security/advisories/GHSA-67c6-q4j4-hccg","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/flarum/framework/security/advisories/GHSA-67c6-q4j4-hccg"},{"name":"https://github.com/flarum/framework/commit/d1059c1cc79fe61f9538f3da55e8f42abbede570","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/flarum/framework/commit/d1059c1cc79fe61f9538f3da55e8f42abbede570"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-02T15:56:22.975991Z","id":"CVE-2023-40033","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-02T16:00:40.870Z"}}]}}
