## What is GHSA-wrrw-crp8-979q?

GHSA-wrrw-crp8-979q is a vulnerability in pageflow, published on 15 Sep 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

### Impact

The attack allows extracting sensitive properties of database objects that are associated with users or entries belonging to an account that the attacker has access to.

Pageflow uses the `ActiveAdmin` Ruby library to provide some management features to its users. `ActiveAdmin` relies on the `Ransack` library to implement search functionality. In its default configuration, `Ransack` will allow for query conditions based on properties of associated database objects [1]. The `*_starts_with`, `*_ends_with` or `*_contains` search matchers [2] can then be abused to exfiltrate sensitive string values of associated database objects via character-by-character brute-force.

### Mitigation

Upgrade to version 15.7.1 or 14.5.2 of the `pageflow` gem.

Affected packages and fixed versions:
- pageflow (RubyGems): affected all versions; fixed in 14.5.2
- pageflow (RubyGems): affected all versions; fixed in 14.5.2
- pageflow (RubyGems): affected from 15.0.0; fixed in 15.7.1

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.
