**Name of the Vulnerable Software and Affected Versions**
CodeChecker (affected versions not specified)
**Description**
The `massStoreRun` processing path performs one-shot decompression of Base64-encoded zlib data without enforcing a maximum decompressed size. An authenticated user with permissions to store analysis runs can submit a highly compressed payload that expands into a significantly larger byte sequence. Since the decompressed output is materialized in memory before being written to a temporary file, a large payload can exhaust process or host memory and consume substantial disk space, leading to a denial of service.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
