FortiGuard Labs reported ongoing in-the-wild exploitation of CVE-2026-48908, a critical CVSS 10.0 unauthenticated remote code execution flaw in the JoomShaper SP Page Builder extension for Joomla. The bug stems from an unrestricted file upload in the asset.uploadCustomIcon functionality that lets attackers upload and execute arbitrary PHP files, enabling full server compromise. Public proof-of-concept exploit code is available, and the vulnerability was added to CISA’s Known Exploited Vulnerabilities catalog after active abuse was confirmed.
FortiGuard said exploitation has remained elevated, with 1,210 blocked attempts in 24 hours and 15,626 over 7 days, indicating sustained automated scanning of Internet-facing Joomla servers. The highest attack volumes were observed against organizations in Poland, Turkey, Australia, and the United States, with Telecommunications/Carrier and Technology among the most targeted sectors. Defenders were urged to upgrade to SP Page Builder 6.6.2 or later, restrict public access to Joomla administrative interfaces, block PHP execution in upload directories, and investigate for web shells, suspicious files, unauthorized administrator accounts, and other persistence because patching alone does not remove an existing compromise.

CISA has added two Joomla extension vulnerabilities to its Known Exploited Vulnerabilities catalog after confirming active exploitation against **SP Page Builder** and **Page Builder CK**. The flaws, tracked as `CVE-2026-48908` and `CVE-2026-56290`, are unauthenticated arbitrary file upload bugs that allow attackers to place malicious files on exposed Joomla sites and achieve remote code execution. Security reporting says the vulnerabilities have been used to upload web shells, deploy PHP file-manager backdoors, and create hidden administrator accounts for persistence on compromised systems. Vendor fixes are available, including **SP Page Builder 6.6.2** for the zero-day issue, and defenders are being urged to patch immediately or temporarily disable the affected extensions and restrict public access to vulnerable upload endpoints until remediation is complete.

A critical vulnerability, **`CVE-2026-56290`**, affects the Joomla **Page Builder CK** extension before version **3.6.0** and allows **unauthenticated arbitrary file upload**. The flaw can let remote attackers upload executable files and achieve **full remote code execution**, and it has been assigned a **CVSS 4.0 score of 10.0**. Belgium’s Centre for Cybersecurity issued a warning urging organizations to patch immediately because exposed Joomla sites using the vulnerable extension could be compromised without authentication. Advisories recommend upgrading **Page Builder CK** to **3.6.0 or later**, restricting upload permissions, and validating allowed file types to reduce exposure. Related vulnerability reporting published at the same time also highlighted a separate critical web CMS plugin issue, **`CVE-2026-57331`**, in the WordPress **Paid Videochat Turnkey Site** plugin through **7.4.8**, where an **arbitrary file deletion** flaw rated **CVSS 9.9** was remediated in **7.4.9** or later, underscoring continued risk from insecure file-handling bugs in widely deployed content management extensions.

CISA added **CVE-2026-48907** to its Known Exploited Vulnerabilities catalog after reports of active exploitation against the Widget Factory **Joomla Content Editor (JCE)** plugin. The maximum-severity improper access control flaw lets unauthenticated attackers create new editor profiles and then upload and execute PHP code, resulting in remote code execution on vulnerable Joomla sites. The KEV update raised the catalog total to 1,622 entries and set a federal remediation deadline of **2026-06-19** under **BOD 26-04**. Vendor and media reporting said the issue affects JCE versions **1.0.0 through 2.9.99.4**, with fixes released in **2.9.99.5** and later, including **JCE Pro 2.9.99.6**. The JCE team also issued a free patch for older sites and warned that public exploit code is available, attacks are automated, and sites without public registration can still be targeted. Security reporting noted that applying the update blocks the initial access path but does not remove any persistence, web shells, or malware that attackers may already have deployed on compromised servers.
