CVE-2026-32641: Parseablehq Parseable

High severity, CVSS 7.5. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Parseablehq Parseable: before 3.0.0 (fixed in 3.0.0)
