Primary sources: NVD · CVE.org · FIRST EPSS

There is a low severity open redirect vulnerability within affected versions of Bitbucket Data Center. Versions of Bitbucket DC from 8.0.0 to 8.9.12 and 8.19.0 to 8.19.1 are affected by this vulnerability. It is patched in 8.9.13 and 8.19.2. This open redirect vulnerability, with a CVSS Score of 3.1 and a CVSS Vector of CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N, allows an unauthenticated attacker to redirect a victim user upon login to Bitbucket Data Center to any arbitrary site which can be utilized for further exploitation which has low impact to confidentiality, no impact to integrity, no impact to availability, and requires user interaction. Atlassian recommends that Bitbucket Data Center customers upgrade to the version. If you are unable to do so, upgrade your instance to one of the supported fixed versions.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
