## What is CVE-2017-11131?

CVE-2017-11131 is a medium-severity vulnerability in n/a, published on 1 Aug 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered in heinekingmedia StashCat through 1.7.5 for Android, through 0.0.80w for Web, and through 0.0.86 for Desktop. For authentication, the user password is hashed directly with SHA-512 without a salt or another key-derivation mechanism to enable a secure secret for authentication. Moreover, only the first 32 bytes of the hash are used. This allows for easy dictionary and rainbow-table attacks if an attacker has access to the password hash.

Weakness: CWE-916 (Use of Password Hash With Insufficient Computational Effort)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2017-11131 and fix it if it is affected.

What it is: CVE-2017-11131 is a medium-severity vulnerability in n/a, published on 1 Aug 2017. 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-2017-11131 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.
