The facts
The vendor identifies all seven PyPI wheels for 1.107.0 published between 11:39:51 and 13:23 UTC on 21 October as compromised. [1]
Affected Docker Hub tags included v1.107.0, latest, main-latest and main-stable during the 11:46:56–14:20 UTC exposure window. The corresponding affected GHCR tags were removed at 13:51 UTC; these are historical exposure windows, not a claim that the tags remain malicious. [1]
LiteLLM says the source-code v1.107.0 tag was clean and its private enterprise registry was unaffected. A clean source tag does not establish that a downloaded build artifact was safe. [1][2]
The vendor’s 23 October postmortem and Upwind’s separate 26 October analysis describe a hijacked release pipeline. Upwind participated in identifying the incident; its analysis is separate from the vendor’s account, but it is an involved security company. [2][3]
Still unconfirmed
- The number of affected installations and the extent of actual credential theft are not established.
- Public download totals do not establish a victim count.
