Re: Retrospective by 'gpg.fail' authors

oss-security thread on the gpg.fail retrospective discusses legacy code removal and flaws surfaced by frontier AI models in open-source projects.

In a reply to Soatok Dreamseeker's gpg.fail retrospective thread on the oss-security mailing list, cryptographer Peter Gutmann argues it is often unclear which legacy code is obsolete or can be safely removed. He recounts a discussion with another well-known open-source project developer estimating, unscientifically, that around half of issues in such projects were found by frontier AI models. The exchange reflects on lessons from documenting weaknesses in GnuPG/OpenPGP implementations.

Unauthenticated attackers are bypassing Cisco ISE’s management interface (CVE-2026-76460)

Cisco confirmed CVE-2026-76460, an actively exploited unauthenticated authentication bypass in Cisco ISE APIs, urging immediate patching with no workarounds available.

Cisco confirmed active exploitation of CVE-2026-76460, caused by insufficient authentication control on an ISE API endpoint. A remote, unauthenticated attacker can send a crafted request to bypass the web-based management interface and gain unauthorized access to affected devices. The flaw affects Cisco ISE and ISE-PIC releases 3.0 through 3.5; fixes are 3.1 Patch 12, 3.2 Patch 11, 3.3 Patch 12, 3.4 Patch 7, and 3.5 Patch 4, with no workarounds. Cisco provided IoCs, advises checking access.log for suspicious usernames, cross-checking firewall and network logs, and re-imaging suspect nodes since attackers may delete ISE logs.

When scanners miss the attack: how Cloudflare Client-Side Security protects storefronts

Cloudflare's Page Shield ML uncovered four malicious JavaScript campaigns on storefronts, including affiliate fraud and a remote-backdoor script, that VirusTotal and URLScan missed.

Cloudflare's Page Shield ML detected four client-side JavaScript operations (eight payloads) in live traffic on online storefronts, enabling affiliate commission hijacking, clickless affiliate theft via hidden iframes, user tracking with a remote-code backdoor, and cloaking of paid mobile visitors. Seven of the eight payloads were absent from VirusTotal and URLScan returned no malicious verdict for any, including a Lnkr-family payload indexed unclassified for roughly 2.5 years. Detection relies on a graph neural network over JavaScript syntax trees, an LLM second opinion on Workers AI, and a frontier-model ensemble voting across benign, magecart, other malware, and cryptomining labels.

First Agentic AI Data Breach Reported to Spanish Regulator

Spain's AEPD reported the first data breach executed by an AI agent, which autonomously chained login, vulnerability discovery, and personal data modification.

Spain's Data Protection Agency (AEPD) published details of the first breach notification in which an AI agent executed the attack, achieving a successful login, searching for vulnerabilities, and modifying personal data and accessing invoices. The agency called the agent's autonomous chaining of attack phases a qualitative change and urged updated risk analysis, faster incident response, and stronger credential protection. Investigation is ongoing; commentators cite possible causes including a guardrail jailbreak, an escaped test model, or an unauthorized LLM-based penetration test.
