Quick Takeaways
- New detection modules address critical pre-authentication and authentication bypass vulnerabilities in Audiobookshelf, LiteLLM Proxy, and Next.js, with CVE-2025-25205, CVE-2026-42208, and CVE-2025-29927, potentially enabling unauthorized access and privilege escalation.
- An exploit for Dalfox Server versions ≤ 2.12.0 allows unauthenticated remote code execution (RCE) via deserialization of the
found-actionparameter, posing significant threat to server integrity. - Ongoing enhancements in brute-force reporting and socket handling improve detection accuracy and operational stability, indirectly strengthening defenses against evasive attack techniques.
Threats, Attack Techniques, and Targets
The latest Metasploit update introduces several new modules that could be used by attackers. These modules target specific vulnerabilities in popular software. For example, there is an unauthenticated API bypass in Audiobookshelf, affecting versions 2.17.0 to 2.19.0. Attackers can exploit this to bypass authentication without needing any credentials.
Another module detects a pre-auth SQL injection vulnerability in LiteLLM Proxy. This flaw, identified as CVE-2026-42208, allows attackers to run malicious SQL commands before any login is required. Similarly, a scanner for CVE-2025-29927 can help identify authorization bypass issues in self-hosted Next.js applications.
There is also an exploit module that targets Dalfox Server versions up to 2.12.0. It lets attackers send malicious data that gets deserialized and executes arbitrary commands. In summary, these new tools focus on vulnerabilities in web applications, servers, and API interfaces, which are often targeted by cybercriminals.
Impact, Security Implications, and Remediation Guidance
The vulnerabilities addressed in these modules have serious security implications. For example, the authentication bypass and pre-auth SQL injection can give attackers unauthorized access to systems. The Dalfox deserialization flaw can allow remote code execution, leading to complete compromise of affected servers.
Organizations should act promptly if they use any of the affected software versions. If these vulnerabilities are present, attackers could manipulate or take control of their systems. To reduce risk, security teams should apply patches or updates provided by the software vendors. Since specific remediation guidance is not included in this brief, organizations should consult the vendors or official security advisories for detailed instructions.
