      <title>CVE-2024-39897 — Cache driver GetBlob() allows read access to any blob without access control check</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-39897</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; project-zot zot&lt;/p&gt;
&lt;p&gt;zot is an OCI image registry. Prior to 2.1.0, the cache driver `GetBlob()` allows read access to any blob without access control check. If a Zot `accessControl` policy allows users read access to some repositories but restricts read access to other repositories and `dedupe` is enabled (it is enabled by default), then an attacker who knows the name of an image and the digest of a blob (that they do not have read access to), they may maliciously read it via a second repository they do have read access to. 
 This attack is possible because [`ImageStore.CheckBlob()` calls `checkCacheBlob()`](https://github.com/project-zot/zot/blob/v2.1.0-rc2/pkg/storage/imagestore/imagestore.go#L1158-L1159) to find the blob a global cache by searching for the digest. If it is found, it is copied to the user requested repository with `copyBlob()`. The attack may be mitigated by configuring &amp;#34;dedupe&amp;#34;: false in the &amp;#34;storage&amp;#34; settings. The vulnerability is fixed in 2.1.0.&lt;/p&gt;</description>
