How this page is checked

StackPrism reads every OSV.dev advisory for paramiko, merges duplicates filed under several ids, and asks OSV.dev which ones affect each version listed. Releases and their dates come from deps.dev, downloads from pypistats.org. No AI writes this page: every sentence comes from that data, refreshed every few hours.

Last checked against OSV.dev, CISA KEV, PyPI, pypistats.org and deps.dev.
