What is CVE-2026-92770?

Harbor versions up to 2.15.2 exhibit insufficient filtering of the q query parameter, allowing project administrators to exploit this weakness. By using fuzzy filtering on the AccessCredential column, attackers can extract the scanner adapter secret iteratively, character by character, leveraging the response row counts. This vulnerability poses significant risks to sensitive credential management and emphasizes the need for robust security measures.

Affected Version(s)

harbor 0 <= 2.15.2

Exploit Proof of Concept (PoC)
