    Unspecified vulnerability in certain versions of xpdf after 3.00, as used in various products including (a) pdfkit.framework, (b) gpdf, (c) pdftohtml, and (d) libextractor, has unknown impact and user-assisted attack vectors, possibly involving errors in (1) gmem.c, (2) SplashXPathScanner.cc, (3) JBIG2Stream.cc, (4) JPXStream.cc, and/or (5) Stream.cc. NOTE: this description is based on Debian advisory DSA 979, which is based on changes that were made after other vulnerabilities such as CVE-2006-0301 and CVE-2005-3624 through CVE-2005-3628 were fixed. Some of these newer fixes appear to be security-relevant, although it is not clear if they fix specific issues or are defensive in nature.

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.
