All of them do that on git information, particularly the branch name, so if the branch has a specially-crafted name the vulnerability can be exploited. **Fixed in**: [b3ba9978](https://github.com/ohmyzsh/ohmyzsh/commit/b3ba9978). **Impacted areas**: - `pygmalion` theme. - `pygmalion-virtualenv` theme. - `refined` theme.
