# CVE-2024-8096: OCSP stapling bypass with GnuTLS > Attackers can bypass OCSP stapling validation in curl when using GnuTLS, allowing connections to servers with invalid certificates. - **Severity:** Medium 6.5 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 11 Sep 2024 - **Updated:** 15 Oct 2026 - **Also known as:** ALPINE-CVE-2024-8096, AZL-49035, AZL-49038, AZL-49041, AZL-49099, AZL-49132, CLEANSTART-2026-XC32509, CURL-CVE-2024-8096, DEBIAN-CVE-2024-8096, DLA-3951-1, GHSA-gv3v-x3f3-7fxm, JLSEC-2026-418, SUSE-SU-2024:3203-1, SUSE-SU-2024:3204-1, SUSE-SU-2024:3211-1, UBUNTU-CVE-2024-8096, USN-7012-1, openSUSE-SU-2024:14333-1 ## What is CVE-2024-8096? CVE-2024-8096 is a medium-severity vulnerability in Debian Debian Linux, published on 11 Sep 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate.

What it is: CVE-2024-8096 is a medium-severity vulnerability in Debian Debian Linux, published on 11 Sep 2024. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2024-8096 in the wild and no public exploit code. Affected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
