Five Critical WordPress Plugin and Theme Flaws Enable Site Takeover or RCE

Five critical flaws (CVSS 9.8–10.0) in WPMU DEV Dashboard, Avada, TranslatePress, Pods, and GiveWP enable WordPress admin takeover and RCE.

Wordfence and Patchstack disclosed five critical flaws in WordPress plugins and themes: WPMU DEV Dashboard, Avada, TranslatePress, Pods, and GiveWP. The issues include unauthenticated authentication bypass (CVE-2026-76581), arbitrary file write leading to RCE (CVE-2026-18431), administrator account takeover via password-reset URL exposure (CVE-2026-19632), privilege escalation (CVE-2026-19598), and PHP object injection to RCE (CVE-2026-82222, CVSS 10.0). Patchstack says the GiveWP flaw chains an unsafe unserialize helper, attacker-controlled donation data, and a gadget chain in shipped code.

Why Johnny Can't Encrypt: A Usability Evaluation of PGP 5.0 (1999)

Seminal 1999 USENIX study finds most novice users cannot correctly sign and encrypt email with PGP 5.0 in 90 minutes.

Whitten and Tygar's USENIX Security Symposium paper evaluates whether cryptography novices can use PGP 5.0 effectively, using cognitive walkthrough analysis and a laboratory user test. The majority of test participants failed to successfully sign and encrypt a message within 90 minutes, despite PGP 5.0 having a well-regarded graphical interface. The authors argue that security requires usability standards beyond those of general consumer software and propose domain-specific UI design principles for security. The paper is a foundational reference in usable security research.

How to opt out of AI chatbot training

Malwarebytes guides users through disabling AI training use of chats in ChatGPT, Perplexity, and Claude after OpenAI's human review program emerged.

404 Media reported that OpenAI's 'Project Lily' hires hundreds of contractors to review ChatGPT prompts, with a 'Privacy Filter' removing personal data and usernames hidden, though user memories summaries can still reveal identifying details. The article provides opt-out steps: ChatGPT Settings > Data Controls > 'Improve the model for everyone' (on by default), Perplexity Settings > Preferences > AI data retention, and Claude Settings > Privacy > 'Help Improve our AI Models'. Opting out does not prevent all human access, which remains allowed for abuse investigation, support, troubleshooting, and legal matters.

Forminator WordPress Flaw Can Enable Unauthenticated RCE via Malicious PHP Uploads

Wordfence disclosed CVE-2026-15748, a critical unauthenticated file upload flaw enabling RCE in the Forminator Forms WordPress plugin, patched in version 1.56.2.

Wordfence reported CVE-2026-15748 (CVSS 9.8) in Forminator Forms, a WordPress plugin with over 600,000 active installations, allowing unauthenticated attackers to upload arbitrary PHP files and achieve remote code execution. The flaw stems from insufficient file type validation in the handle_file_upload() function, and exploitation requires a form containing both a File Upload field and a Select field, plus a custom upload storage root lacking .htaccess PHP protection. All versions up to and including 1.56.1 are affected; version 1.56.2 released July 31, 2026 fixes the issue. Wordfence also disclosed CVE-2026-15826 (CVSS 9.8), an authentication bypass in User Profile Builder (40,000+ installs) letting unauthenticated attackers log in as administrator, fixed in version 3.16.5 on July 16, 2026.

Why User Studies and Participant Experience Reporting Matter for VR Motion Privacy?

User studies explain VR motion privacy mechanism acceptance far better than physical deviation metrics, a study of three mechanisms finds.

The paper examines how well physical deviation predicts user acceptance of VR motion privacy mechanisms compared to user studies, testing three mechanisms at five deviation levels. User studies explain substantially more variation in mechanism acceptance, though physical deviation remains significant, and prior VR experience affects acceptance. Public VR game leaderboards expose motion recordings from hundreds of thousands of users, creating identification and profiling risks. The authors recommend combining physical deviation metrics with user studies and reporting participants' prior experience.

Chrome DevTools Technique Enables Authenticated Session Hijacking in Live Windows Browsers

SpecterOps released CDP-Enable-BOF, a Beacon Object File that enables Chrome DevTools Protocol in live Chrome or Edge processes on Windows for session hijacking.

SpecterOps released CDP-Enable-BOF, an x64 Beacon Object File that activates Chrome DevTools Protocol inside running chrome.exe or msedge.exe processes on Windows, exposing cookies, history, saved passwords, and authenticated sessions without administrator rights. It calls Chromium's StartRemoteDebuggingServer on the browser UI thread to stay reliable under CFG, TLS, and CET, and was tested on Chrome 147 and Edge 147. The technique builds on work by DeathFlamingo and Cedric Van Bockhaven; Google had hardened remote debugging in Chrome 136 after attackers used it to steal cookies post-App-Bound Encryption. Defenders can watch Sysmon Event IDs 8 and 10 for injection into browser processes.

Can We Stop The Ads? Taxonomy and Characterization of Smartphone Splash Ads and Existing Countermeasures

Study of 108 ad-defense implementations finds only one tool blocked splash-ad navigation across ten popular apps, and it required Accessibility permission.

The paper taxonomizes smartphone splash ads — full-screen ads at app launch that trick users into trigger mechanisms such as moving the phone — and analyzes 108 documented advertising defenses for deployment barriers. Many defenses require device rooting, jailbreaking, runtime code injection, or application modification; others need extra permissions, rule maintenance, compilation, or payment. In evaluating 13 configurations of 11 tools across 10 popular apps, only one prevented ad-triggered navigation across all ten apps, requiring Accessibility permission and leaving ads visible roughly one second before dismissal. Documented harms include delayed emergency response, driver distraction, and degraded accessibility for vision-impaired users.

Have it both ways: stay discoverable in search while disallowing AI training

Cloudflare launches Disallow AI Training setting letting sites block AI training via robots.txt while staying indexed in search; Apple, Google, and Microsoft honor it.

Cloudflare announced a 'Disallow AI Training' setting that publishes a no-training preference in robots.txt so sites can block AI training (including by mixed-use crawlers) without losing search indexing. Apple, Google, and Microsoft meet Cloudflare's new 'Accountable' designation, which requires training/summary opt-out mechanisms, URL-level training visibility, and assurance that opt-outs don't affect search rankings. Cloudflare cites that under 1% of its sites block search bots while 17% block AI training, and its Block settings now apply to mixed-use crawlers as well. Granular controls over how much content appears in AI summaries are planned for early next year.

Ask HN: How do you manage skills files?

A Hacker News thread debates whether agent skill files are worth managing, citing 2–4x output-token reductions on flagship models in one company's testing.

Commenters argue skills are stored prompts that help less-technical users compensate for weak prompting, while one participant reports company testing found skills reduce flagship-model output tokens by roughly 2–4x, a gap growing with newer models. Others note skills can bundle reusable scripts and inline commands for deterministic context building, and that harnesses now execute backticked commands before the agent sees the skill. Some argue improving model capability makes downloadable skills redundant.

Don't Trust the Super-App: A Case Study of Russia's Max

Researchers show super-apps like Russia's Max can silently capture mini-app UI, storage, network traffic, and authentication, enabling untraceable user impersonation.

The paper challenges the assumption that super-apps are trusted intermediaries, citing WeChat's passive cross-mini-app tracking, Russia's Max's entanglement with state prosecution of online speech, and Iran's Bale operating during a prolonged internet shutdown. Using Max as a case study, the authors demonstrate that a super-app can capture mini-app UI, read and write mini-app local storage, inject arbitrary JavaScript into mini-app runtimes, mediate network traffic, and control authentication context, enabling silent user impersonation without trace. They argue these capabilities are inherent to the super-app architecture and call for mobile OS and app store interventions to close the blind spot.
