Is your app affected by CVE-2026-114612?
Paste this prompt into Claude Code, Cursor or any AI coding tool: it runs a free Shippable scan of your project and fixes what it finds. Built with Lovable, Bolt or v0? Scan your live app. Or upload your package file.
Who is affected
litellm(PyPI) >= 1.91.0, < 1.100.4litellm(PyPI) >= 1.101.0, < 1.101.3litellm(PyPI) >= 1.102.0, < 1.102.2litellm(PyPI) >= 1.103.0, < 1.103.1litellm(PyPI) >= 1.104.0rc1, < 1.104.0rc2
How to check
- Run
pip show litellmin your project to see the installed version, including copies pulled in by other packages. - Or paste your lockfile into the checker: it lists every package with a known vulnerability, this one included.
- Or run
npx shippable-dev scan localhost:3000in your project folder. It reads your lockfile and flags this vulnerability along with every other known one.
How to fix
Copies a prompt for Claude Code, Cursor or Codex: it checks your lockfiles for this and upgrades it.
- On >= 1.91.0, < 1.100.4: Upgrade
litellmto 1.100.4 or later, commit the lockfile and redeploy. - On >= 1.101.0, < 1.101.3: Upgrade
litellmto 1.101.3 or later, commit the lockfile and redeploy. - On >= 1.102.0, < 1.102.2: Upgrade
litellmto 1.102.2 or later, commit the lockfile and redeploy. - On >= 1.103.0, < 1.103.1: Upgrade
litellmto 1.103.1 or later, commit the lockfile and redeploy. - On >= 1.104.0rc1, < 1.104.0rc2: Upgrade
litellmto 1.104.0rc2 or later, commit the lockfile and redeploy. - If a vulnerable version was live, check your logs and rotate the secrets that server could read.
The advisory
### Summary
An authenticated user with `internal_user` privileges can escalate to `proxy_admin` and achieve remote code execution. The proxy uses one encryption key for two purposes: sealing secrets at rest and minting session tokens. An attacker exploits this by requesting a new API key with a crafted metadata field containing a forged admin credential as the "secret" value. The proxy encrypts and returns this payload. When this value is then presented as a bearer token, the proxy decrypts it, trusts the forged admin identity, and grants full administrative access, including the ability to execute arbitrary commands via the MCP stdio endpoint.
### Affected versions
Versions later than 1.91.0 are exploitable in the default configuration. Versions 1.87.0 through 1.90.x are exploitable only if `EXPERIMENTAL_UI_LOGIN=true` was explicitly set.
### Mitigation
Upgrade to a patched version as soon as possible.
If you cannot upgrade immediately, set `EXPERIMENTAL_UI_LOGIN=false`. This disables the vulnerable authentication path but also breaks CLI SSO and Claude Code gateway login.
### Impact
An internal user can escalate to proxy admin and execute arbitrary commands on the host.
