    Direct static code injection vulnerability in edit.php in ACal Calendar Project 2.2.5 allows authenticated users to execute arbitrary PHP code via (1) the edit=header value, which modifies header.php, or (2) the edit=footer value, which modifies footer.php. NOTE: this issue might be resultant from the poor authentication as identified by CVE-2006-0182. Since the design of the product allows the administrator to edit the code, perhaps this issue should not be included in CVE, except as a consequence of CVE-2006-0182.

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.
