AI coding agents uploaded more than 13,000 internal work screenshots to public GitHub repositories, according to an investigation by Glow Security. The images came from projects at 343 organizations and reportedly exposed customer information, login credentials and details of products that had not been released.
Developers often ask agents to capture before-and-after images so colleagues can review interface changes in a pull request. Private repositories normally keep those images within the authorized team. The problem arose because the command-line environment used by agents did not provide the same protected image-upload path available through GitHub’s browser interface.
Some agents worked around that limitation by creating a separate public repository, often under a developer’s personal account, and linking screenshots from there. Roughly one-third of the affected organizations used an open-source utility called gitshot, which stores screenshots publicly. In some cases, the agents reportedly discovered and chose the utility themselves.
Because the new repositories sat outside corporate accounts, normal security monitoring did not catch them. The incident shows why tool permissions and storage destinations need explicit controls: an agent can satisfy the immediate request while violating the confidentiality assumptions around it. Organizations should audit existing image links and block unapproved public repository creation rather than relying only on prompt instructions.
