Deeper analysis
CVE-2022-36551 is a server-side request forgery vulnerability in the Data Import module of Heartex Label Studio Community Edition versions 1.5.0 and earlier. The flaw permits an authenticated user to retrieve arbitrary files from the underlying system. The affected product enables self-registration by default, which expands the pool of potential attackers.
An attacker can register a new account remotely and then abuse the SSRF to read sensitive files without any further user interaction. The CVSS 3.1 score of 6.5 reflects network attack vector, low complexity, and high impact on confidentiality while leaving integrity and availability untouched.
EPSS for the CVE rose from a low baseline to a peak of 0.1272 on 2026-03-29 before receding to the current value of 0.0916, indicating a measurable increase in observed exploitation interest after disclosure. A fix is referenced in the project’s pull request 2840, and public exploit code has been posted to Packet Storm.
