EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.1 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 88% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

@misskey-dev/summaly is a tool for getting a summary of a web page. Starting in version 3.0.1 and prior to version 5.2.1, a logic error in the main summaly function causes the allowRedirects option to never be passed to any plugins, and as a result, isn't enforced. Misskey will follow redirects, despite explicitly requesting not to. Version 5.2.1 contains a patch for the issue.
