Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
A vulnerability classified as critical exists in DedeCMS version 5.7.109 within an unknown function of the file co_do.php. Manipulation of the rssurl argument triggers server-side request forgery, corresponding to CWE-918. The issue carries a CVSS 3.1 score of 5.5 reflecting an adjacent-network vector, low attack complexity, and low privileges required.
An authenticated attacker on the local network can supply a crafted rssurl value to coerce the server into issuing arbitrary requests, resulting in limited impacts to confidentiality, integrity, and availability. Public exploit code for this flaw has been released.
The associated EPSS score stands at 0.8124 with no indicated rise from a lower baseline. References point to a GitHub repository containing technical details of the SSRF vector and to Vuldb entries that catalog the issue.
