Background for this topic.
GitHub is a hosted software-development platform built around Git repositories. It supports public and private source-code hosting, change review through pull requests, issue tracking, automated workflows, and package distribution. Its repositories and automation are important security assets because they can contain proprietary code, deployment instructions, credentials, and the components used to build released software.
Material risks include accidentally committing secrets, exposing private repositories through misconfigured permissions, and allowing compromised dependencies or workflow actions to run in trusted build environments. Pull requests from untrusted contributors can also become an execution path when workflows handle them unsafely. Security practice includes least-privilege access, strong authentication, protected branches and required reviews, secret scanning and rapid credential revocation, and auditing workflow permissions. Repository history, dependency metadata, and commit provenance can support vulnerability management and incident investigation, but deleting a leaked secret from the latest file does not remove it from historical commits or existing clones.

If you can't bother to keep GitHub running, why should we bother with you? Opinion It's been another shabby week for Microsoft, and a shabbier one for its users. We learnt that Windows 11's epic habit of trying to corral customers into paid-for Microsoft services just got worse with a low-rent trick. Remote Desktop got a bit more secure, which is good, but in a way that suggests not too much user testing took place. As for GitHub… GitHub got two helpings of Chef Redmondo's Special Sauce.…
This CVSS 10.0 RCE vuln has been patched, automatically for some, so better check those workflows If you use Gemini CLI, watch out: Google has patched a CVSS 10.0 vulnerability in its command-line AI tool and is warning anyone running it in headless mode, or through GitHub Actions, to review their workflows.…
Claude ploughs through months of work in rapid time, helps Wiz researchers nab lucrative award
Claude ploughs through months of work in rapid time, helps Wiz researchers nab lucrative award Wiz researchers are set for a tidy payday thanks to their discovery of a high-severity flaw in GitHub's git infrastructure that handed remote attackers full read/write access to private GitHub repositories using a single command.…
Vendor confirms repo data exposure after Lapsus$ claims source code, secrets dump Software security testing outfit Checkmarx has become the latest organization caught up in an ongoing attack on security-tool providers. The biz said data posted online appears to have come from one of its GitHub repositories after the Lapsus$ extortion crew claimed to have dumped the company’s source code, secrets, and other sensitive data.…
Researchers who found the flaws scored beer money bounties and warn the problem is probably pervasive Exclusive Security researchers hijacked three popular AI agents that integrate with GitHub Actions by using a new type of prompt injection attack to steal API keys and access tokens, and the vendors who run agents didn’t disclose the problem.…
