Plugin4Shell defeats the SHA pinning that locks reviewed plugins in four AI coding agents

AIR says Claude Code, Codex, GitHub Copilot and Gemini CLI all check out a pinned plugin commit without verifying they landed on it, so a trusted plugin can be swapped for attacker code during a background auto-update. Anthropic and OpenAI have patched.

Plugin4Shell turned a pinned commit into attacker code in four AI coding agents

Researchers at AIR found that four AI coding agents accepted a Git checkout they never verified, and because no marketplace can close the gap, the repair now travels through agent version numbers inside each enterprise.

Trusting the repository author in VS Code runs the fake recruiter's task file

Microsoft's Defender Experts date the Contagious Interview campaign to December 2022. Its payload lands at the one hiring stage where a candidate is expected to clone and run a stranger's code. The same team tells employers to give staff a non-persistent VM for coding tests.

Opting into native Git in SageMaker Unified Studio turns every save into a staging decision

Auto-sync put whatever sat on disk into Git history, notebook outputs and stray credentials included. File-level staging fixes that, and it also breaks every handoff a team built on the assumption that saving was enough.

Harness gives the coding agent its own permissions and its own audit trail

The pitch rests on a claim about your repository rather than about Harness's software, and with a free tier and click-through migration, the expensive part of testing it is the wiring you would have to move.

A repo compromise found in week four outlives GitHub's seven-day Git event log

Wiz CIRT's poster puts 88 percent of its customers on hosted version control, where Git read and write events age out in a week and the fix, streaming them somewhere else, often sits behind a higher license tier.

The agent said the Jira move failed. It had already committed the write.

A step-limit abort was reported as a task failure after the transition had gone through. The harness described its own loop, not the system of record, and a retry was one keystroke away.
