CVE-2026-32641: CWE-248: Uncaught Exception in parseablehq parseable
Parseable versions prior to 3.0.0 contain a vulnerability where the HTTP middleware uses unwrap() on the x-amz-firehose-common-attributes header before authentication. An unauthenticated remote attacker can send malformed or non-UTF-8 header data to trigger a Rust panic, causing denial of service by interrupting request handling or causing container restart loops. This issue is fixed in version 3.0.0.
AI Analysis
Technical Summary
Parseable, a log analytics platform, has a vulnerability (CVE-2026-32641) in versions before 3.0.0 where the HTTP middleware source code uses unwrap() on the x-amz-firehose-common-attributes header without proper error handling. This allows a remote unauthenticated attacker to supply malformed JSON, non-UTF-8 data, or invalid header values that cause a Rust panic, interrupting request processing and enabling denial of service conditions such as repeated request failures or container restart loops. The vulnerability is addressed in version 3.0.0.
Potential Impact
The vulnerability allows a remote unauthenticated attacker to cause a denial of service by triggering a Rust panic in the HTTP middleware during header parsing. This can interrupt request handling and potentially cause container restart loops, impacting availability. There is no impact on confidentiality or integrity.
Mitigation Recommendations
Upgrade Parseable to version 3.0.0 or later, where this issue is fixed. No other mitigations are indicated.
