## What is CVE-2020-15526?

CVE-2020-15526 is a medium-severity vulnerability in n/a, published on 9 Jul 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Redgate SQL Monitor 7.1.4 through 10.1.6 (inclusive), the scope for disabling some TLS security certificate checks can extend beyond that defined by various options on the Configuration > Notifications pages to disable certificate checking for alert notifications. These TLS security checks are also ignored during monitoring of VMware machines. This would make SQL Monitor vulnerable to potential man-in-the-middle attacks when sending alert notification emails, posting to Slack or posting to webhooks. The vulnerability is fixed in version 10.1.7.

Weakness: CWE-295 (Improper Certificate Validation)

Check this codebase for CVE-2020-15526 and fix it if it is affected.

What it is: CVE-2020-15526 is a medium-severity vulnerability in n/a, published on 9 Jul 2020. 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-2020-15526 in the wild and no public exploit code.

Affected product: n/a. 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.
