A new vulnerability affects GitHub Copilot and Cursor, allowing attackers to inject malicious code suggestions into these AI-powered coding assistants. By crafting prompts that exploit predictable code generation patterns, attackers can trick the tools into producing vulnerable code snippets, which unsuspecting developers might then integrate into their projects. This "prompt injection" attack doesn't rely on exploiting the tools themselves but rather manipulates the AI models into becoming unwitting accomplices, generating exploitable code like insecure command executions or hardcoded credentials. This poses a serious security risk, highlighting the potential dangers of relying solely on AI-generated code without careful review and validation.
Security researchers exploited a vulnerability in Gemini's sandboxed Python execution environment, allowing them to access and leak parts of Gemini's source code. They achieved this by manipulating how Python's pickle module interacts with the restricted environment, effectively bypassing the intended security measures. While claiming no malicious intent and having reported the vulnerability responsibly, the researchers demonstrated the potential for unauthorized access to sensitive information within Gemini's system. The leaked code included portions related to data retrieval and formatting, but the full extent of the exposed code and its potential impact on Gemini's security are not fully detailed.
Hacker News users discussed the Gemini hack and subsequent source code leak, focusing on the sandbox escape vulnerability exploited. Several questioned the practicality and security implications of running untrusted Python code within Gemini, especially given the availability of more secure and robust sandboxing solutions. Some highlighted the inherent difficulties in completely sandboxing Python, while others pointed out the existence of existing tools and libraries, like gVisor, designed for such tasks. A few users found the technical details of the exploit interesting, while others expressed concern about the potential impact on Gemini's development and future. The overall sentiment was one of cautious skepticism towards Gemini's approach to code execution security.
The popular GitHub Action tj-actions/changed-files was compromised and used to inject malicious code into projects that utilized it. The attacker gained access to the action's repository and added code that exfiltrated environment variables, secrets, and other sensitive information during workflow runs. This action, used by over 23,000 repositories, became a supply chain vulnerability, potentially affecting numerous downstream projects. The maintainers have since regained control and removed the malicious code, but users are urged to review their workflows and rotate any potentially compromised secrets.
Hacker News users discussed the implications of the tj-actions/changed-files compromise, focusing on the surprising longevity of the vulnerability (2 years) and the potential impact on the 23,000+ repositories using it. Several commenters questioned the security practices of relying on third-party GitHub Actions without thorough vetting, emphasizing the need for auditing dependencies and using pinned versions. The ease with which a seemingly innocuous action could be compromised highlighted the broader security risks within the software supply chain. Some users pointed out the irony of a security-focused action being the source of vulnerability, while others discussed the challenges of maintaining open-source projects and the pressure to keep dependencies updated. A few commenters also suggested alternative approaches for achieving similar functionality without relying on third-party actions.
The blog post details a vulnerability in the "todesktop" protocol handler, used by numerous applications and websites to open links directly in desktop applications. By crafting malicious links using this protocol, an attacker can execute arbitrary commands on a victim's machine simply by getting them to click the link. This affects any application that registers a custom todesktop handler without properly sanitizing user-supplied input, including popular chat platforms, email clients, and web browsers. This vulnerability exposes hundreds of millions of users to potential remote code execution attacks. The author demonstrates practical exploits against several popular applications, emphasizing the severity and widespread nature of this issue. They urge developers to immediately review and secure their implementations of the todesktop protocol handler.
Hacker News users discussed the practicality and ethics of the "todesktop" protocol, which allows websites to launch desktop apps. Several commenters pointed out existing similar functionalities like URL schemes and Progressive Web Apps (PWAs), questioning the novelty and necessity of todesktop. Concerns were raised about security implications, particularly the potential for malicious websites to exploit the protocol for unauthorized app launches. Some suggested that proper sandboxing and user confirmation could mitigate these risks, while others remained skeptical about the overall benefit outweighing the security concerns. The discussion also touched upon the potential for abuse by advertisers and the lack of clear benefits compared to existing solutions. A few commenters expressed interest in legitimate use cases, like streamlining workflows, but overall the sentiment leaned towards caution and skepticism due to the potential for malicious exploitation.
A malicious VS Code extension masquerading as a legitimate "prettiest-json" package was discovered on the npm registry. This counterfeit extension delivered a multi-stage malware payload. Upon installation, it executed a malicious script that downloaded and ran further malware components. These components collected sensitive information from the infected system, including environment variables, running processes, and potentially even browser data like saved passwords and cookies, ultimately sending this exfiltrated data to a remote server controlled by the attacker.
Hacker News commenters discuss the troubling implications of malicious packages slipping through npm's vetting process, with several expressing surprise that a popular IDE extension like "Prettier" could be so easily imitated and used to distribute malware. Some highlight the difficulty in detecting sophisticated, multi-stage attacks like this one, where the initial payload is relatively benign. Others point to the need for improved security measures within the npm ecosystem, including more robust code review and potentially stricter publishing guidelines. The discussion also touches on the responsibility of developers to carefully vet the extensions they install, emphasizing the importance of checking publisher verification, download counts, and community feedback before adding any extension to their workflow. Several users suggest using the official VS Code Marketplace as a safer alternative to installing extensions directly via npm.

HN commenters discuss the potential for malicious prompt injection in AI coding assistants like Copilot and Cursor. Several express skepticism about the "vulnerability" framing, arguing that it's more of a predictable consequence of how these tools work, similar to SQL injection. Some point out that the responsibility for secure code ultimately lies with the developer, not the tool, and that relying on AI to generate security-sensitive code is inherently risky. The practicality of the attack is debated, with some suggesting it would be difficult to execute in real-world scenarios, while others note the potential for targeted attacks against less experienced developers. The discussion also touches on the broader implications for AI safety and the need for better safeguards against these types of attacks as AI tools become more prevalent. Several users highlight the irony of GitHub, a security-focused company, having a product susceptible to this type of attack.
The Hacker News post titled "New Vulnerability in GitHub Copilot, Cursor: Hackers Can Weaponize Code Agents" has generated a number of comments discussing the potential security implications of AI-powered code generation tools.
