# CVE-2025-9943: Unauthenticated SQL Injection Vulnerability in Shibboleth Service Provider > Unauthenticated attackers can extract arbitrary database data via blind SQL injection when the replay cache uses an SQL database with ODBC. - **Severity:** Critical 9.1 (`CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/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:** 10 Sep 2025 - **Updated:** 4 Nov 2025 - **Also known as:** DEBIAN-CVE-2025-9943, DLA-4300-1, DSA-5994-1, GHSA-p7fp-v35q-pm7j, SUSE-SU-2026:22854-1, SUSE-SU-2026:3098-1, SUSE-SU-2026:3123-1, UBUNTU-CVE-2025-9943, USN-8768-1, openSUSE-SU-2025:15714-1, openSUSE-SU-2026:21418-1 ## What is CVE-2025-9943? CVE-2025-9943 is a critical SQL injection vulnerability in Shibboleth Service Provider, published on 10 Sep 2025. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description An SQL injection vulnerability has been identified in the "ID" attribute of the SAML response when the replay cache of the Shibboleth Service Provider (SP) is configured to use an SQL database as storage service. An unauthenticated attacker can exploit this issue via blind SQL injection, allowing for the extraction of arbitrary data from the database, if the database connection is configured to use the ODBC plugin. The vulnerability arises from insufficient escaping of single quotes in the class SQLString (file odbc-store.cpp, lines 253-271). This issue affects Shibboleth Service Provider through 3.5.0.

What it is: CVE-2025-9943 is a critical SQL injection vulnerability in Shibboleth Service Provider, published on 10 Sep 2025. 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-2025-9943 in the wild and no public exploit code. Affected product: Shibboleth Service Provider. 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.
