"A threshold has been reached. We are effectively being DDoSed. If we could, we would charge them for this waste of our time," wrote Daniel Stenberg, original author and lead of the curl project, on LinkedIn this week.

Curl (cURL in some realms), which turned 25 years old in 2023, is an essential command-line tool and library for interacting with Internet resources. The open source project receives bug reports and security issues through many channels, including HackerOne, a reporting service that helps companies manage vulnerability reporting and bug bounties. HackerOne has fervently taken to AI tools in recent years. "One platform, dual force: Human minds + AI power," the firm's home page reads.

Stenberg, saying that he's "had it" and is "putting my foot down on this craziness," suggested that every suspected AI-generated HackerOne report will have its reporter asked to verify if they used AI to find the problem or generate the submission. If a report is deemed "AI slop," the reporter will be banned. "We still have not seen a single valid security report done with AI help," Stenberg wrote.

Three critical vulnerabilities in multiple virtual-machine products from VMware can give hackers unusually broad access to some of the most sensitive environments inside multiple customers’ networks, the company and outside researchers warned Tuesday.

The class of attack made possible by exploiting the vulnerabilities is known under several names, including hyperjacking, hypervisor attack, or virtual machine escape. Virtual machines often run inside hosting environments to prevent one customer from being able to access or control the resources of other customers. By breaking out of one customer’s isolated VM environment, a threat actor could take control of the hypervisor that apportions each VM. From there, the attacker could access the VMs of multiple customers, who often use these carefully controlled environments to host their internal networks.

All bets off

“If you can escape to the hypervisor you can access every system,” security researcher Kevin Beaumont said on Mastodon. “If you can escape to the hypervisor, all bets are off as a boundary is broken.” He added: “With this vuln you’d be able to use it to traverse VMware managed hosting providers, private clouds orgs have built on prem etc.”

Thousands of sites running WordPress remain unpatched against a critical security flaw in a widely used plugin that was being actively exploited in attacks that allow for unauthenticated execution of malicious code, security researchers said.

The vulnerability, tracked as CVE-2024-11972, is found in Hunk Companion, a plugin that runs on 10,000 sites that use the WordPress content management system. The vulnerability, which carries a severity rating of 9.8 out of a possible 10, was patched earlier this week. At the time this post went live on Ars, figures provided on the Hunk Companion page indicated that less than 12 percent of users had installed the patch, meaning nearly 9,000 sites could be next to be targeted.

Significant, multifaceted threat

“This vulnerability represents a significant and multifaceted threat, targeting sites that use both a ThemeHunk theme and the Hunk Companion plugin,” Daniel Rodriguez, a researcher with WordPress security firm WP Scan, wrote. “With over 10,000 active installations, this exposed thousands of websites to anonymous, unauthenticated attacks capable of severely compromising their integrity.”
