Vulnerabilities & ExploitsExploiting SSTI Vulnerability in Messenger Machine on Standoff 365 Leads to RCE and Corporate Chat Access
A detailed writeup published by Positive Technologies researcher Seven11eleven demonstrates a full attack chain against the vulnerable Messenger machine on the Standoff 365 platform. The researcher began with network reconnaissance using nmap and directory fuzzing with ffuf, uncovering Swagger documentation and JWT-protected endpoints. After identifying user enumeration through the friend search feature, the team discovered a Server-Side Template Injection flaw in the friendship summary functionality powered by the Mako template engine. The SSTI was escalated to remote code execution by injecting Python expressions that leveraged the self.module.cache.util chain to call os.popen commands. With initial access obtained via reverse shell, the attacker pivoted to neighboring services including Gitness, RabbitMQ, and Redis to achieve the defined business risks of accessing developer corporate messaging and extracting the city messenger encryption key.
Developer Exposes 12 Vulnerabilities in FastAPI Todo App After 176 Bots Bypass Protections
A developer building a student-focused todo planner on FastAPI discovered that 176 of 238 new accounts were bots that bypassed three layers of protection including rate limiting and email verification. The issues stemmed from in-memory counters reset on every deployment, uvicorn trusting any X-Forwarded-For header, and email verification never being enforced in code. A full audit revealed additional flaws such as stored XSS via JSON-LD on public Q&A pages and an IDOR allowing any authenticated user to read all tasks in a project by supplying its ID. Fixes included moving rate limits to the database, properly extracting the client IP from the rightmost X-Forwarded-For entry, adding signed form timestamps, and escaping JSON for script contexts. The case highlights common pitfalls when deploying Python web services behind nginx without strict trust boundaries.
Browser Policy Manager 0.9.5 Release Candidate Adds Comprehensive Multi-Language Documentation Portal
Browser Policy Manager (BPM) is approaching its 1.0.0 release as an open-source tool designed for preparing, validating, and exporting Firefox Enterprise policy profiles. The 0.9.5 update introduces four current Firefox schema channels including Release 153, ESR 153.0, ESR 140.13, and ESR 115.38, along with migration assistance from older ESR versions. A full documentation portal built in DITA now ships with the product, covering user guides, Firefox policy references, CIS benchmark mappings, and administrator instructions across six languages. The portal integrates directly with the BPM interface through manifests and UI target maps, providing contextual help without server dependencies. Local search uses static indexes with deterministic ranking, while future RAG capabilities are planned with strict source verification and no model training on documentation. The project emphasizes reproducible builds, locale completeness checks, and clear separation between automated mappings and manual compliance validation.
