Published: 31 March 2023
Summary
CVE-2023-27163 is a medium-severity SSRF (CWE-918) vulnerability in Rbaskets Request Baskets. Its CVSS base score is 6.5 (Medium).
Operationally, ranked in the top 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Request-baskets versions up to 1.2.1 contain a server-side request forgery vulnerability in the /api/baskets/{name} endpoint. The flaw is tracked as CVE-2023-27163 and carries a CVSS 3.1 score of 6.5; it is also identified under CWE-918. An authenticated user can supply a crafted request that causes the application to fetch arbitrary network resources on the attacker’s behalf.
Because the vector requires high privileges (PR:H) and no user interaction, an administrator or similarly privileged account can exploit the issue to reach internal systems and retrieve sensitive data that would otherwise be inaccessible. The current EPSS score of 0.9332 matches its recorded peak, indicating sustained exploitation interest since disclosure.
Public references include exploit code on Packet Storm and a technical write-up on GitHub, but no vendor advisory or patch details are provided in the available sources.
