Nuclei Templates Added for WordPress SSTI and Nginx UI Access Control Flaws
ProjectDiscovery contributors opened and advanced Nuclei template pull requests for two newly tracked vulnerabilities: CVE-2026-4257, a server-side template injection issue in the WordPress Contact Form by Supsystic plugin, and CVE-2026-33032, a broken access control flaw in Nginx UI. The GitHub activity shows template development intended to support detection of both issues, with one pull request referencing a new CVE-2026-4257.yaml file and another marked ready to merge for the Nginx UI vulnerability.
The available records are limited to repository metadata and do not include technical write-ups, affected version ranges, exploitation details, or vendor remediation guidance. Even so, the publication of detection content for these CVEs indicates that security researchers are operationalizing checks for exposed systems, and defenders using Nuclei should watch for template releases covering both the WordPress plugin SSTI and the Nginx UI authorization weakness.

ProjectDiscovery Adds Nuclei Checks for WordPress, Synway, and XSS Flaws
ProjectDiscovery's `nuclei-templates` repository received several pull requests adding or refining detection logic for newly disclosed web vulnerabilities. Proposed templates covered **CVE-2026-0561** for cross-site scripting, **CVE-2025-69411** for a high-severity path traversal/local file read in the WordPress plugin `ioncube-tester-plus`, **CVE-2026-1405** for a critical SSRF issue in a WordPress REST API endpoint, and an unauthenticated remote command execution flaw in **Synway SMG Gateway** via `9-2radius.php`. The submissions generally reported validation against vulnerable and patched targets to reduce false positives, with several marked ready for merge pending maintainer review. The WordPress `ioncube-tester-plus` template demonstrated file disclosure through `loader-wizard.php` by abusing the `ininame` parameter to retrieve `/etc/passwd`, while the `slider-future` WordPress template showed SSRF by sending an external `image_url` to `/wp-json/slider-future/v1/upload-image/` and confirming outbound DNS interaction through OAST. The Synway SMG Gateway submission described command injection through the `radius_address` parameter reaching a `system()` call, but automated review flagged template quality problems including weak matching logic and missing metadata. Separately, a fix was proposed for the **CVE-2025-71243** template after reports of frequent false positives, replacing reflection-based checks with `md5`-based proof of code execution to improve accuracy.

Nuclei Templates Added for Ghost CMS SQLi and n8n Form Node RCE
ProjectDiscovery's public `nuclei-templates` repository received new detection content for two newly tracked web application flaws: **CVE-2026-26980** in Ghost CMS and **CVE-2026-27493** in n8n. One pull request adds a template for a Ghost CMS **SQL injection** issue, with the contributor reporting validation against both vulnerable and patched targets to improve detection accuracy and reduce false positives. A second pull request adds coverage for a **critical unauthenticated expression injection** flaw in n8n Form nodes that can lead to remote code execution. The n8n issue affects versions earlier than **2.10.1**, **2.9.3**, and **1.123.22**, and the proposed template targets the `/form/contact-us` endpoint. The submission says attacker-controlled expressions in form fields are double-evaluated by the server, allowing arbitrary shell command execution; the detection logic verifies exploitation by looking for Linux `uid`/`gid` output after running a command in a controlled test. Both submissions were reported as validated on vulnerable and patched hosts and entered the standard GitHub review workflow, signaling rapidly emerging scanner coverage for high-impact Ghost CMS and n8n exposures.

Nuclei Templates Added for MITRE Caldera RCE and GitLab SAML Auth Bypass
ProjectDiscovery contributors submitted new Nuclei detection templates for two newly tracked vulnerabilities: **`CVE-2025-27364`**, described as an **unauthenticated remote code execution** flaw in **MITRE Caldera**, and **`CVE-2025-25291`**, an **authentication bypass** issue in **`ruby-saml`** affecting **GitLab SAML SSO** deployments. The references indicate both issues were significant enough to prompt rapid addition of scanning coverage in the public `nuclei-templates` repository. Available details remain limited because the source material is drawn from GitHub pull request metadata rather than full advisories, but the vulnerability labels point to potentially high-impact exposure in identity and adversary-emulation infrastructure. Security teams using **GitLab SAML single sign-on** or **MITRE Caldera** should track vendor guidance, validate exposure to **`CVE-2025-25291`** and **`CVE-2025-27364`**, and prepare to use updated detection content as part of vulnerability assessment workflows.
