A critical vulnerability in the WordPress W3 Total Cache plugin allows remote, unauthenticated attackers to execute arbitrary PHP commands on affected sites. Tracked as CVE-2025-9501, the flaw affects versions earlier than 2.8.13 and is tied to insufficient validation of user input in the plugin’s _parse_dynamic_mfunc() function. According to CSIRT.SK, the bug can be triggered through a specially crafted comment, creating a path to full system compromise on vulnerable WordPress installations.
The issue carries a CVSS v3 score of 9.0, underscoring the risk to organizations running the plugin in production. Security updates were released by the vendor in W3 Total Cache 2.8.13, and defenders are being urged to upgrade immediately and review WordPress databases, site files, and logs for evidence of exploitation or malicious post-compromise activity.

A critical vulnerability (CVE-2025-9501) has been identified in the W3 Total Cache WordPress plugin, affecting versions prior to 2.8.13. This flaw allows unauthenticated attackers to execute arbitrary PHP commands on affected sites by submitting a specially crafted comment, exploiting the `_parse_dynamic_mfunc` function. The vulnerability has been assigned a CVSS score of 9.0, indicating a high risk of remote code execution, and potentially impacts up to 1 million WordPress sites using the vulnerable plugin version. Security researchers warn that exploitation of this vulnerability could allow attackers to fully compromise WordPress installations without authentication, leading to site defacement, data theft, or further malware deployment. Administrators are strongly advised to update W3 Total Cache to version 2.8.13 or later to mitigate the risk, as the vulnerability is remotely exploitable and poses a significant threat to a large number of websites.

WordPress released security updates for two core vulnerabilities, **CVE-2026-63030** and **CVE-2026-60137**, that can be chained to make a blind SQL injection remotely reachable without authentication and, in some cases, lead to **remote code execution**. The issue, dubbed **`wp2shell`**, stems from REST API batch-route confusion in the `/wp-json/batch/v1` endpoint combined with SQL injection, affecting WordPress versions **6.9.0 through 6.9.4** and **7.0.0 through 7.0.1**. Researchers said the route-confusion flaw carries a **CVSS 9.8** rating, while the second SQL injection bug is rated **CVSS 5.9**. WordPress fixed the flaws in **6.9.5** and **7.0.2**, and also backported the SQL injection fix to **6.8.6**. The vulnerabilities were reported by Adam Kues of Assetnote through the WordPress HackerOne program, and while exploitation had not been confirmed at the time of disclosure, a public proof of concept later became available, increasing the risk of rapid weaponization. Administrators were urged to verify that forced automatic updates succeeded and, if immediate patching was not possible, to apply mitigations such as blocking the REST batch endpoint with a WAF.

Two high-severity vulnerabilities have been disclosed in widely deployed WordPress plugins, exposing internet-facing sites to **unauthenticated compromise**. `CVE-2026-3584` affects **Kali Forms** through version `2.4.9` and allows **remote code execution** because user-controlled input can be mapped into internal placeholder storage and later invoked via `call_user_func` in the `form_process` path. The issue is classified as `CWE-94` and carries a `CVSS 3.1` score with the vector `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`, indicating critical impact on confidentiality, integrity, and availability. A second flaw, `CVE-2026-4038`, affects **Aimogen Pro** through version `2.7.5` and enables **unauthenticated privilege escalation** through an arbitrary function call in `aiomatic_call_ai_function_realtime` caused by a missing capability check. According to the disclosure, attackers can invoke WordPress functions such as `update_option` to change the default registration role to administrator and enable user registration, effectively creating a path to full site takeover. The vulnerability is tracked as `CWE-862` and was likewise rated with a high-impact `CVSS 3.1` vector of `AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`.
