CVE-2025-46511 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Derek Springer BeerXML Shortcode plugin, affecting versions up to 0.71. SSRF vulnerabilities occur when an attacker can manipulate a server-side application to make HTTP requests to arbitrary domains or internal systems that the server can access. In this case, the BeerXML Shortcode plugin, which is likely used to parse or embed BeerXML data within web content, improperly validates or sanitizes user-supplied input that controls outbound requests. This flaw enables an attacker to coerce the server into sending crafted requests to internal or external resources, potentially bypassing network restrictions or firewalls. The vulnerability is categorized under CWE-918, which specifically addresses SSRF issues. Although no known exploits are currently reported in the wild and no official patches have been released, the presence of this vulnerability poses a risk of unauthorized internal network scanning, data exfiltration, or interaction with internal services that are not otherwise exposed to the internet. The plugin’s exact usage context is not detailed, but given its function related to BeerXML (a data format for beer recipes), it is plausible that it is deployed on websites or content management systems related to brewing communities or businesses. The vulnerability was published on April 24, 2025, and is marked with medium severity by the source, Patchstack, but lacks a formal CVSS score. The absence of authentication or user interaction requirements is not explicitly stated, but SSRF vulnerabilities often can be triggered by unauthenticated users if the vulnerable functionality is publicly accessible.

For European organizations, the SSRF vulnerability in BeerXML Shortcode could lead to several security risks. If exploited, attackers might leverage the vulnerability to access internal network resources, including sensitive databases, internal APIs, or cloud metadata services, potentially leading to data leakage or further compromise. Organizations using this plugin on public-facing websites could inadvertently expose internal infrastructure details or enable lateral movement within their networks. This is particularly concerning for small to medium enterprises in the brewing industry or related sectors that may rely on niche plugins like BeerXML Shortcode without extensive security oversight. Additionally, if the plugin is integrated into larger content management systems or e-commerce platforms, the SSRF could be a stepping stone for more complex attacks, including privilege escalation or supply chain compromise. The medium severity rating suggests a moderate risk, but the actual impact depends on the deployment context and network segmentation. Given the lack of known exploits, immediate widespread impact is unlikely, but the vulnerability represents a latent risk that could be exploited once publicly disclosed or weaponized.

To mitigate this SSRF vulnerability, European organizations using the BeerXML Shortcode plugin should: 1) Immediately audit their web applications to identify instances of the BeerXML Shortcode plugin and assess exposure. 2) Restrict outbound HTTP requests from web servers to only trusted domains using network-level controls such as egress filtering and firewall rules, minimizing the risk of SSRF exploitation. 3) Implement input validation and sanitization at the application level to ensure that any user-supplied URLs or parameters cannot be manipulated to access internal or unauthorized resources. 4) Monitor web server logs and network traffic for unusual outbound requests that could indicate SSRF attempts. 5) Engage with the plugin vendor or community to track the release of official patches or updates addressing this vulnerability and apply them promptly once available. 6) Consider deploying Web Application Firewalls (WAFs) with SSRF detection capabilities to block suspicious request patterns. 7) If possible, isolate the plugin’s execution environment to limit the potential impact of exploitation, such as running it in a containerized or sandboxed environment. These steps go beyond generic advice by focusing on network-level controls and proactive monitoring tailored to SSRF risks.
