CISA has added two CVSS 10.0 arbitrary file upload flaws in the iCagenda and Balbooa Forms Joomla extensions to its Known Exploited Vulnerabilities catalog after confirmed in-the-wild exploitation. Federal agencies must patch by July 13 while all Joomla administrators are advised to update to the fixed versions released in June and July.
Attackers can upload arbitrary files, including PHP scripts, through the file attachment feature, leading to data theft, web shell installation, and full website compromise.
The vulnerability permits upload of dangerous file types such as executables, resulting in remote code execution and complete site takeover.
These maximum-severity RCEs via unauthenticated uploads highlight why extension inventories and rapid patching remain non-negotiable for any Joomla deployment.

Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
CISA added CVE-2026-65660, a Microsoft SharePoint code injection vulnerability, to its Known Exploited Vulnerabilities catalog on September 25, with a federal deadline of September 28. The flaw could let an authorized attacker execute code over a network and carries a Microsoft CVSS 3.1 score of 8.8.
CISA added MikroTik RouterOS flaw CVE-2026-67279 to its Known Exploited Vulnerabilities catalog on September 25, with a federal deadline of September 28. The SSH bug lets an unauthenticated client open a session channel and send an exec request, and CISA says it can be chained with CVE-2026-86060. Fixed RouterOS versions are available.
CISA placed the actively exploited F5 BIG-IP APM heap-based buffer overflow CVE-2026-94127 into its KEV catalog on 2026-09-22 with a three-day remediation deadline for federal agencies. The zero-day enables unauthenticated remote code execution on systems running both an access policy and OAuth profile on the same virtual server, prompting immediate patching and forensic triage.
IBM has released patches addressing nine vulnerabilities in Guardium Data Protection across versions 12.0 through 12.2.2. Two of the flaws are rated critical and could allow remote attackers to seize control of edge clusters or execute scripts in user browsers.
