CVE-2026-32641

Parseable: Unauthenticated Denial of Service via panic in Kinesis header parsing middleware

Published Sep 18, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
Parseable is a log analytics platform built for high-volume data ingestion and analysis. Prior to 3.0.0, src/handlers/http/middleware.rs uses unwrap() while parsing the x-amz-firehose-common-attributes header before authentication. A remote unauthenticated attacker can supply non-UTF-8 header data, malformed JSON, or invalid derived header values that trigger a Rust panic and interrupt request handling, allowing repeated requests to deny service or cause container restart loops. This issue is fixed in version 3.0.0.
