    Spring Boot DevTools remote secret comparison is vulnerable to timing attacks

    CVE-2026-40972 · GHSA-56v8-86gj-66jp

    Affected
    • Maven org.springframework.boot:spring-boot-devtools >= 4.0.0, < 4.0.6; >= 3.5.0, < 3.5.14; >= 3.4.0, <= 3.4.15; >= 3.3.0, <= 3.3.18; <= 2.7.32
    Fixed in
    4.0.63.5.14· Partial vendor fix
    Issue
    An attacker on the same network as the remote application may be able to utilize a timing attack to discover information about the remote secret. In extreme circumstances this could result in the attacker determining the secret and uploading changed classes, thereby achieving remote code execution in the remote application. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); DevTools remote secret comparison. Versions that are no longer supported are also affected per vendor advisory.

    Recommended action: Upgrade to 4.0.6 or 3.5.14 by release line; some affected versions have no fix yet, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
