    ProjeQtor versions 7.0 through 12.4.3 contain a stored cross-site scripting vulnerability in the file upload functionality where the checkValidFileName() function fails to restrict HTML and HTM file uploads. Authenticated attackers can upload HTML files containing arbitrary JavaScript through the image upload or attachment endpoints, and any user accessing the uploaded file URL will execute the embedded JavaScript in their browser.

  • Apr 3, 2025A vulnerability was found in Projeqtor up to 12.0.2.CVE-2025-3169 · Other software · reported by VulDBLow 2.3

    A vulnerability was found in Projeqtor up to 12.0.2. It has been rated as critical. Affected by this issue is some unknown functionality of the file /tool/saveAttachment.php. The manipulation of the argument attachmentFiles leads to unrestricted upload. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 12.0.3 is able to address this issue. It is recommended to upgrade the affected component. The vendor explains, that "this vulnerability can be exploited only on not securely installed instances, as it is adviced during product install: attachment directory should be out of web reach, so that even if executable file can be uploaded, it cannot be executed through the web."

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.
