## What is CVE-2026-0993?

CVE-2026-0993 is a high-severity memory corruption vulnerability in SODOLA SL902-SWTGW124AS, published on 15 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

SODOLA SL902-SWTGW124AS firmware before 200.2.12 contains a buffer overflow vulnerability that allows unauthenticated remote attackers to cause a denial of service by sending an oversized boundary value in the Content-Type header of a crafted POST request. Attackers can exploit the embedded HTTP server's multipart/form-data boundary parser to cause the device to become fully unresponsive — dropping all management access and traffic forwarding during its self-recovery cycle.

Weakness: CWE-120 (Buffer Copy without Checking Size of Input)

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.
