FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

rgw: improperly verified POST keys
IBM Spectrum Fusion HCI 2.5.2 through 2.7.2 could allow an attacker to perform unauthorized actions in RGW for Ceph due to improper bucket access. IBM X-Force ID: 266807.
A flaw was found in rgw. This flaw allows an unprivileged user to write to any bucket(s) accessible by a given key if a POST's form-data contains a key called 'bucket' with a value matching the bucket's name used to sign the request. This issue results in a user being able to upload to any bucket accessible by the specified access key as long as the bucket in the POST policy matches the bucket in the said POST form part.
