Simon Willison summarises Parameter Labs' ChatGPT account takeover chain against the HTML previews (formerly Canvas) sandboxed iframe. A postMessage handler from the MathLive virtual keyboard used innerHTML, letting sandboxed code inject an unsandboxed iframe. A YouTube oEmbed endpoint allowed by the CSP reflected JavaScript, enabling exfiltration of private data via a ChatGPT share URL. OpenAI fixed it and paid a $5,000 bounty.

Parameter Labs describes a chain that turned a public ChatGPT share link into JavaScript running as chatgpt.com in the victim's session. It combined a MathLive postMessage listener with no origin or source check, raw HTML in keyboard layouts, an unsandboxed srcdoc iframe, and a YouTube oEmbed JSONP callback to pass the CSP. The code read private conversations through backend APIs. OpenAI fixed it on 26 October 2026 and rated it P1.

Huntress researcher Andrew Schwartz demonstrates a novel OAuth token-theft technique: a sideloaded AppX package registered via Add-AppxPackage -Register (requiring only Developer Mode, no admin beyond that toggle) can set ContentUriRules WindowsRuntimeAccess="all" so attacker-controlled JavaScript rendered inside the Microsoft-signed WWAHost.exe process gets full WinRT access, including the legacy WebAuthenticationBroker OAuth API. Using Microsoft Office's own client ID and the oob redirect URI, the attacker triggers a genuine login.microsoftonline.com/MFA dialog with no browser chrome, captures the auth code, and exchanges it for an access token plus a long-lived refresh token carrying the full Office delegated Graph scope set (mail, files, Teams, directory, AuditLog.Create) — validated end-to-end against a live Entra ID tenant with MFA and default Conditional Access. The post frames it as a class of vulnerable signed AppX host binaries sharing the same WinRT activation layer, and provides a Sigma rule keyed on the MSAppHost/3.0 EdgeHTML user agent reaching non-Microsoft destinations, plus Sysmon/Event ID and GPO-based mitigations (restricting Developer Mode, Conditional Access, shorter refresh-token lifetimes, CAE).

This paper introduces predicted-state matching, a training objective for discriminative world models used by web agents to rank candidate actions at test time. Unlike standard supervised next-state prediction (predicting HTML/AXTree snapshots), the objective trains models to distinguish the true resulting state from alternative-action outcomes, better aligning with downstream ranker/PRM use. Trained on a branching dataset derived from WebArena Go-Browse trajectories, the approach improves PRM-style action ranking on WebPRMBench and end-to-end task success on WebArena-Lite.

An attacker with contributor access to one project can hide prompt-injection instructions inside an HTML comment in a PR description (invisible in the Azure DevOps UI but returned verbatim by the API), which hijacks a reviewing victim's AI agent (tested with Copilot CLI and Claude Code) into running pipelines and reading a confidential wiki page in a separate project the attacker can't access, then exfiltrating the content back as a PR comment — a classic confused-deputy / lethal-trifecta scenario.

Johann Rehberger's writeup of his DEF CON Singapore talk detailing a multi-stage exploit chain against Microsoft 365 Copilot and Consumer Copilot (CVE-2026-24299): indirect prompt injection triggers Copilot's HTML preview feature, CSS background-image/font-face rules bypass img-src CSP and exfiltrate data over font-src, and the attack is made zero-click by instructing Copilot to auto-open the preview. It further chains this with abuse of Copilot's record_memory / durable-facts long-term memory tools (which have no audit logging) to plant persistent "SpAIware"-style instructions that silently exfiltrate any password or secret the user later types, plus Delayed Tool Invocation as a reliability trick and edge_navigate_to abuse in Edge's Copilot to leak stored memories. Includes full disclosure timeline (Oct 2025 report to Dec 2025/Mar 2026 fixes) and broader lessons on CSP not being a reliable AI security boundary and the "lethal trifecta."

Socket's Threat Research Team analyzed "VPN Go: Free VPN" (Chrome Web Store, extension ID jgpfgonjjolillilkjfkiddakagkkpoj) and "Free VPN by VPN GO" (Firefox Add-ons), showing both shipped clean initial versions that later received malicious updates adding clipboard-monitoring "clipper" logic. The extensions poll the clipboard every 500ms (Chrome) or 1.5s (Firefox), chunk newly copied text, and exfiltrate it via GET requests to hardcoded IPs (178.236.252.133, 178.236.252.161, 77.91.123.187) at /html/continue.php, while real proxy/VPN functionality is retained as cover. The writeup includes deobfuscated code, version-by-version infrastructure changes, file hashes, bearer tokens, and MITRE ATT&CK technique mapping for defenders.

Varonis Threat Labs details SearchLeak, a three-stage exploit chain (CVE-2026-42824, critical) that abuses Microsoft 365 Copilot Enterprise Search: a Parameter-to-Prompt (P2P) injection via the search URL's `q` parameter turns a clicked link into an AI instruction, an HTML-rendering race condition lets an injected `<img>` tag fire before Copilot's `<code>`-block sanitizer applies, and Bing's "Search by Image" endpoint (allowlisted in the CSP) performs a server-side fetch that exfiltrates the stolen data to an attacker's server. A single click on a trusted microsoft.com link lets an attacker silently exfiltrate emails, security codes, calendar data, and SharePoint/OneDrive content with the victim's full Graph permissions, no plugins or extra permissions required. Microsoft has patched the issue; the post is a follow-up to Varonis' earlier "Reprompt" finding in Copilot Personal.

BleepingComputer covers Varonis's SearchLeak research, a three-stage attack chain (CVE-2026-42824, now patched) affecting Microsoft 365 Copilot Enterprise Search. Attackers craft a URL with a malicious 'q' parameter to prompt-inject Copilot into searching a victim's mailbox/OneDrive/SharePoint, exploit an HTML-rendering race condition to slip an unsanitized img tag past output neutralization, then abuse an SSRF in Bing's "Search by Image" feature to bypass CSP and exfiltrate the stolen data (emails, passwords, meeting details) to an attacker-controlled server via a single click, no user typing required.

Huntress SOC dissects a multi-stage infection chain that begins with a malspam HTML attachment routed through a legitimate Google DoubleClick tracking link to evade reputation filters, before landing on a self-personalizing phishing kit and dropping a ZIP with a heavily obfuscated JScript loader. The chain cascades through PowerShell droppers into a .NET stager that performs extensive anti-analysis/anti-sandbox checks, disables Windows Defender, patches AMSI (via NtManageHotPatch on Windows 11 24H2) and ETW at the native API level, and uses RunPE process hollowing into InstallUtil.exe or MSBuild.exe to run a final loader that communicates over AES/RSA-encrypted, protobuf-serialized TCP C2 with certificate pinning. The writeup includes GPU-fingerprinting behavior, persistence via registry Run keys and randomized scheduled tasks, and concrete detection/hardening recommendations.

Oasis Security researchers chained three Claude.ai/claude.com vulnerabilities, dubbed "Claudy Day", into an end-to-end attack: hidden HTML tags in the claude.ai/new?q= URL parameter injected invisible instructions into a pre-filled prompt, which then directed Claude to search the victim's conversation history and exfiltrate sensitive data by writing it to a file and uploading it via the Anthropic Files API to an attacker-controlled account (abusing that api.anthropic.com is allowed through the sandbox's network restrictions). A separate open redirect at claude.com/redirect/<target> let attackers weaponize a trusted-looking Google Ads link to silently deliver victims to the injection URL, requiring no MCP servers or integrations. The prompt injection issue has been fixed by Anthropic; remaining issues are being addressed.

MorphKatz is a static C++20 Windows x64 tool that rewrites PE binaries and raw shellcode into semantically identical but byte-different variants using a Zydis-powered CFG-aware disassembler/encoder, YAML rewrite rules, and EFLAGS liveness tracking. It targets two audiences: detection engineers who can measure what percentage of their YARA/Defender/Elastic/Sigma rules survive N polymorphic variants (--variants, --target, --bisect against a live Defender via MpCmdRun), and authorized red-teamers who need reproducible, seed-based, rule-cited evasion runs with JSON/HTML diff reports for engagement deliverables. It explicitly excludes ML-behavioral evasion and live pop-malware obfuscation, restricting mutations to author-audited, semantically-proven equivalence rules.

An XSS in esbuild's dev server, present since 2022: escapeForHTML does not escape double quotes, yet its output was placed inside an href attribute in the directory listing. A folder name containing a quote breaks out of the attribute, and the payload adds a full-screen style plus an onmouseover handler. The fix swapped in escapeForAttribute. Maintainers merged it but said the dev server assumes a trusted environment, so it was not a security vulnerability.

A DFIR analysis by dfir.ch dissecting a real-world phishing campaign that abuses the Windows "search-ms" URI protocol handler embedded in an HTML attachment ("Booking_Confirmation.html") to trigger a WebDAV connection via rundll32/davclnt.dll, present a spoofed Explorer search result, and lure the victim into executing an LNK file. The LNK launches a headless conhost.exe pulling an obfuscated batch script (new.bat) over a trycloudflare.com tunnel, which drops a decoy PDF, downloads a full Python interpreter (FTSP.zip) and additional scripts, and ultimately performs shellcode injection. The post also documents Sysmon process-create telemetry and the HKCU WordWheelQuery registry key as forensic artifacts of the search-ms query.

The author examines Chrome's pre-89 defense that blocks outbound requests to http/https URLs containing both '<' and newline characters, a mitigation against HTML dangling-markup/XSS exfiltration. He shows the restriction only applied to http/https and demonstrates bypassing it by exfiltrating HTML content via a dangling `<meta http-equiv="refresh">` tag pointed at an `ftp://` URL, captured with a netcat FTP listener. The bug was reported to Chromium, which responded by dropping FTP and Gopher scheme support in Chrome 89, killing the bypass.
