    Logrus is vulnerable to DoS when using Entry.Writer()

    CVE-2025-65637 · GHSA-4f99-4q7p-p3gh

    Affected
    • Go github.com/sirupsen/logrus < 1.8.3; >= 1.9.0, <= 1.9.0; >= 1.9.2, <= 1.9.2
    Fixed in
    1.8.31.9.31.9.1· Vendor fix available
    Issue
    A denial-of-service vulnerability exists in github.com/sirupsen/logrus when using Entry.Writer() to log a single-line payload larger than 64KB without newline characters. Due to limitations in the internal bufio.Scanner, the read fails with "token too long" and the writer pipe is closed, leaving Writer() unusable and causing application unavailability (DoS). This affects versions < 1.8.3, 1.9.0, and 1.9.2. The issue is fixed in 1.8.3, 1.9.1, and 1.9.3+, where the input is chunked and the writer continues to function even if an error is logged.

    Recommended action: Upgrade to 1.9.3, 1.9.1 or 1.8.3 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
