An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0.
An issue was discovered in OpenStack Swift before 2.28.1, 2.29.x before 2.29.2, and 2.30.0. By supplying crafted XML files, an authenticated user may coerce the S3 API into returning arbitrary file contents from the host server, resulting in unauthorized read access to potentially sensitive data. This impacts both s3api deployments (Rocky or later), and swift3 deployments (Queens and earlier, no longer actively developed).

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
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.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
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.
