Oct 12, 2026QGIS is a free, open source, cross-platform geographic information system.CVE-2026-104140 · Other software · qgis · reported by GitHubMedium 6.1
QGIS is a free, open source, cross-platform geographic information system. Prior to 3.44.12 and 4.0.0 through 4.2.3, QGIS Server renders feature data in WFS3 (OGC API Features) HTML responses without HTML escaping. Attacker-controlled feature.properties values from a published writable vector layer reach resources/server/api/ogc/templates/wfs3/getFeatures.html through QgsServerOgcApiHandler::htmlDump and the if_nullptr_null_str callback. A user who opens an items HTML page can execute stored markup or script in the QGIS Server origin, which can expose the viewer's session data or issue authenticated requests with the viewer's privileges. This issue is fixed in version 3.44.12.

QGIS is a free, open source, cross platform geographical information system (GIS) The repository contains a GitHub Actions workflow called "pre-commit checks" that, before commit 76a693cd91650f9b4e83edac525e5e4f90d954e9, was vulnerable to remote code execution and repository compromise because it used the `pull_request_target` trigger and then checked out and executed untrusted pull request code in a privileged context. Workflows triggered by `pull_request_target` ran with the base repository's credentials and access to secrets. If these workflows then checked out and executed code from the head of an external pull request (which could have been attacker controlled), the attacker could have executed arbitrary commands with elevated privileges. This insecure pattern has been documented as a security risk by GitHub and security researchers. Commit 76a693cd91650f9b4e83edac525e5e4f90d954e9 removed the vulnerable code.

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.
