CVE-2026-44302: CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') in brantburnett Snappier
Snappier is a high performance C# implementation of the Snappy compression algorithm. Prior to 1.3.1, Snappier.SnappyStream enters an uncatchable infinite loop when decompressing a malformed framed-format Snappy stream as small as 15 bytes. This vulnerability is fixed in 1.3.1.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-44302 affects Snappier versions before 1.3.1. When decompressing a malformed framed-format Snappy stream, the Snappier.SnappyStream component can enter an infinite loop with an unreachable exit condition, causing the application to hang indefinitely. This is classified under CWE-835 (Loop with Unreachable Exit Condition). The vulnerability does not impact confidentiality or integrity but results in a high-severity availability impact (denial of service). The issue is resolved in Snappier version 1.3.1.
Potential Impact
The vulnerability causes a denial of service by making the affected application enter an uncatchable infinite loop during decompression of malformed input. There is no impact on confidentiality or integrity. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Upgrade to Snappier version 1.3.1 or later, where this infinite loop vulnerability is fixed. Since the vendor has released a fixed version, applying this official update is the recommended remediation. Patch status is confirmed by the vendor's versioning information.
