    fzf vulnerable to denial of service through quadratic HTTP request-body accumulation

    CVE-2026-53433 · GHSA-mvmf-94v6-879g

    Affected
    • Go github.com/junegunn/fzf < 0.73.1
    Fixed in
    0.73.1· Vendor fix available
    Issue
    fzf is vulnerable to a Denial of Service (DoS) due to inefficient HTTP body processing in the --listen mode due to inefficient HTTP body processing using repeated string concatenation, resulting in quadratic time complexity (O(n²)). A crafted POST request with many small segments can trigger excessive CPU usage during request handling.This allows a single malicious request to monopolize the single‑threaded HTTP server, blocking all other clients and resulting in denial of service. This issue was fixed in version 0.73.1.

    Recommended action: Upgrade to 0.73.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
