Vulnerability AssessmentAI

Risk Assessment	The CVSS v4.0 vector (AV:N/AC:L/PR:L) indicates network-accessible attack vector, low attack complexity, and requirement for low-privileged authenticated user. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated user with access to the RSS Feed Parser upload or configuration feature provides a malicious RSS feed URL or manipulates an existing feed parameter to point to an internal resource such as http://localhost:8080/admin or http://169.254.169.254/latest/meta-data/ (AWS metadata). The server makes the request on behalf of the attacker without validation, allowing discovery of internal services, credential leakage, or reconnaissance of the cloud infrastructure. …
Remediation	Upgrade SourceCodester RSS Feed Parser to a patched version released by the vendor; no specific fixed version number is confirmed in available data. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
