GPT-5.5 vs Claude Opus 4.7: I Made Both Build an App - Here's What Happened

GPT-5.5 vs Claude Opus 4.7 - two flagship AI models dropped one week apart, and both claim to be the best at agentic coding. We put that to the test by giving each model the exact same prompt: build a production-ready, secure note-taking application from scratch. But we didn't stop at reviewing the code. We actually tried to break it by running real security tests against each app to see whether AI-generated code can be trusted with user data. The results were not what we expected.

Vulnerability Brokers Are Making MILLIONS Off Your Code #zeroday #darkweb

Not every undisclosed bug is undiscovered; some are quietly sold through brokers to whoever pays the most. Governments, criminal groups and private buyers all compete in a shadow market where valuable software flaws become products long before the public ever hears about them.

Emerging Threat: (CVE-2026-41940) cPanel & WHM Authentication Bypass via CRLF Injection

CVE-2026-41940 is a pre-authentication remote authentication bypass in cPanel and WHM caused by a CRLF (Carriage Return Line Feed) injection in the login and session handling logic. An unauthenticated remote attacker can inject raw \r\n characters into a malicious basic authorization header, which cpsrvd then writes into a session file without sanitization.

Threat Brief: CVE-2026-41940: Critical cPanel & WHM Authentication Bypass Actively Exploited in the Wild

CVE-2026-41940 is a critical authentication bypass vulnerability in cPanel & WHM, including DNSOnly, and WP Squared. The issue affects cPanel software versions after 11.40 and can allow an unauthenticated remote attacker to gain unauthorized access to exposed hosting control panels. cPanel released patched versions and published official remediation and detection guidance.

cPanel and WHM Authentication Bypass Vulnerability (CVE-2026-41940)

In late April 2026, a critical authentication bypass vulnerability was disclosed in cPanel and WHM, tracked as CVE-2026-41940. The issue affects the login flow of these widely deployed hosting control panels and allows a remote, unauthenticated attacker to gain administrative access. Given the prevalence of cPanel across shared and dedicated hosting environments, the vulnerability represents a significant management plane risk.

AI finds the vulnerabilities, but exploiting them is a different problem.

AI finds the vulnerabilities, but exploiting them is a different problem. How Sophos Endpoint defends in the AI era, and what the public record on Mythos shows. When Mozilla shipped Firefox 150 with fixes for 271 issues identified by Anthropic’s Mythos model, the headlines focused on the count. The detail that mattered was further down: Mozilla credited only three CVEs to the model. The remaining 268 were classified as defense-in-depth, hardening, or bugs in code paths that could not be exploited.

AI just became the world's most dangerous exploit writer. Here's why Sophos Endpoint is built to stop it.

AI just became the world's most dangerous exploit writer. Here's why Sophos Endpoint is built to stop it. AI-generated zero-days are here. Sophos Endpoint was architected to stop exploits that have never been seen before — blocking the techniques every attack must use, at the moment of execution, with no signature, no cloud lookup, and no configuration required.

CVE-2026-42208: Pre-Authentication SQL Injection in LiteLLM Exposes API Credentials

A critical vulnerability in LiteLLM is turning AI infrastructure into an open vault; no login required. Tracked as CVE-2026-42208, this vulnerability allows attackers to extract API keys, cloud credentials, and provider authentication tokens without any credentials or prior access to the system. The root cause is fundamental lapse in input handling. LiteLLM’s API key validation blindly injects the Bearer token from the Authorization header into a SQL query without sanitization.

Proof-of-concept exploit available for Linux 'Copy Fail' vulnerability (CVE-2026-31431)

On April 29, 2026, details about the ‘Copy Fail’ vulnerability (CVE-2026-31431) were publicly disclosed. This high-severity (CVSS score of 7.8) privilege escalation vulnerability impacts Linux distributions shipped since 2017. It allows an unprivileged local user to obtain root-level access on affected Linux systems by corrupting the kernel’s in-memory page cache of a privileged binary.
