New Skyvern RCE
A new module has landed this week targeting Skyvern versions 0.1.84 and below, exploiting a server-side template injection (SSTI) vulnerability to gain remote code execution. Tracked as CVE-2025-49619, the issue lets an authenticated user upload a malicious workflow that executes arbitrary commands on the server. The exploit abuses Python internals exposed through a templating engine to run the payload. If you’ve got a valid API key, this one is reliable, stealthy, and effective.

Description: Adds a new exploits/linux/http/skyvern_ssti_cve_2025_49619 module for exploiting a server side template injection vulnerability in Skyvern <= 0.1.84. It requires an API_KEY to create a malicious workflow and gain remote code execution.
Enhancements and features (1)
- #20289 from cgranleese-r7 - This adds support to Metasploit's module references to tag content with IDs from the MITRE ATT&CK framework. This also adds search capabilities for these new IDs that are aware of their hierarchical structure.
Bugs fixed (2)
- #20346 from zeroSteiner - This fixes an issue with the php_fpm_rce module, which stopped working after adding a new encoder that increased the size of payload. This addresses this issue and substitutes the original encoder for smaller base64 encoder.
- #20362 from sjanusz-r7 - Fixes a crash when running the modules/auxiliary/scanner/ssl/bleichenbacher_oracle module with an older version of Python.
