Feb 12, 2024Pixelfed is an open source photo sharing platform.CVE-2024-25108 · Other software · pixelfed · reported by GitHubCritical 9.9
Pixelfed is an open source photo sharing platform. When processing requests authorization was improperly and insufficiently checked, allowing attackers to access far more functionality than users intended, including to the administrative and moderator functionality of the Pixelfed server. This vulnerability affects every version of Pixelfed between v0.10.4 and v0.11.9, inclusive. A proof of concept of this vulnerability exists. This vulnerability affects every local user of a Pixelfed server, and can potentially affect the servers' ability to federate. Some user interaction is required to setup the conditions to be able to exercise the vulnerability, but the attacker could conduct this attack time-delayed manner, where user interaction is not actively required. This vulnerability has been addressed in version 0.11.11. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
