The flaws reside in the text annotation feature's deserialization logic, where Zoom allocates four fixed 128-byte buffers without checking packet size, enabling buffer overflow attacks. An attacker merely needs to be present in a meeting to silently execute malicious code on all other participants' systems. A single researcher at A Security discovered and built a working exploit using fewer than 20 AI prompts in under 24 hours. Mitigations include updating clients, disabling E2EE to allow server-side filtering, enforcing minimum client version policies, and disabling unused features like annotation, whiteboarding, and file transfer. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the CVEs for the Zoom zero-click RCE vulnerabilities and which versions are affected? The vulnerabilities are CVE-2026-53413 (buffer overflow), CVE-2026-53415 (use-after-free), and CVE-2026-53414 (missing bounds check causing denial-of-service), all affecting Zoom client applications before versions 7.1.5 and 7.0.6. A related path traversal flaw, CVE-2026-53416, affects Zoom Workplace VDI Client and VDI Plugins for Windows before versions 7.0.11 and 6.6.15, and also impacts Zoom Rooms and Zoom Meeting SDK before version 7.1.0. _Teams patching Zoom clients can track new CVEs and fixes as they land on daily.dev._ ### How did the researcher who found the Zoom RCE vulnerabilities use AI to build the exploit? A researcher from A Security used an AI agent on publicly available AI models to go from finding the flaw to building a working exploit using fewer than 20 prompts in under 24 hours. The firm stated this level of capability previously required nation-state resources, elite teams, months of effort, and large budgets, but a single researcher achieved a nation-state-level exploit in under a day. _Security teams weighing AI-assisted exploit research risks can follow findings like this on daily.dev._ ### How can I mitigate the Zoom zero-click RCE vulnerability in annotation without immediately updating every client? Disable end-to-end encryption (E2EE) for meetings so Zoom's server-side mitigation can filter malicious annotation messages, since E2EE prevents the server from inspecting and filtering them. Also set minimum client versions in meeting preferences to block unpatched clients, enforce waiting rooms, passcodes, and authenticated-users-only joining, and lock annotation, file transfer, whiteboarding, remote control, and third-party apps. _Admins hardening meeting security settings can keep up with mitigation guidance like this on daily.dev._ ## Similar posts on daily.dev - [Zoom and GitLab Release Security Updates Fixing RCE, DoS, and 2FA Bypass Flaws](https://daily.dev/posts/zoom-and-gitlab-release-security-updates-fixing-rce-dos-and-2fa-bypass-flaws-nu967rvz1) · The Hacker News · 0 upvotes · 0 comments - [Zoom warns of critical account takeover vulnerability](https://daily.dev/posts/zoom-warns-of-critical-account-takeover-vulnerability-n5d4se3mt) · BleepingComputer · 1 upvotes · 0 comments --- Tags: [#zoom](https://daily.dev/tags/zoom) [View this post on daily.dev](https://daily.dev/posts/zoom-zero-click-rce-flaws-allow-attackers-to-compromise-meeting-participants-nkm8hdvlk) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Zoom zero-click RCE flaws allow attackers to compromise meeting participants","url":"https://daily.dev/posts/zoom-zero-click-rce-flaws-allow-attackers-to-compromise-meeting-participants-nkm8hdvlk","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/zoom-zero-click-rce-flaws-allow-attackers-to-compromise-meeting-participants-nkm8hdvlk"},"datePublished":"2026-08-11T23:00:24.343Z","dateModified":"2026-09-14T08:23:43.042Z","description":"Zoom has patched four vulnerabilities, including two zero-click remote code execution flaws (CVE-2026-53413 and CVE-2026-53415) affecting all Zoom client...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/36059c299bd7abb18592ac74ee7c7200?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/36059c299bd7abb18592ac74ee7c7200?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"CSO Online","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"CSO Online","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/98667e4b5cac46cf9c470819c6cf71cd","url":"https://daily.dev/sources/csoonline"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/zoom-zero-click-rce-flaws-allow-attackers-to-compromise-meeting-participants-nkm8hdvlk","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":2},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"zoom","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"CSO Online","item":"https://daily.dev/sources/csoonline"},{"@type":"ListItem","position":3,"name":"Zoom zero-click RCE flaws allow attackers to compromise meeting participants"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/zoom-zero-click-rce-flaws-allow-attackers-to-compromise-meeting-participants-nkm8hdvlk#faq","mainEntity":[{"@type":"Question","name":"What are the CVEs for the Zoom zero-click RCE vulnerabilities and which versions are affected?","acceptedAnswer":{"@type":"Answer","text":"The vulnerabilities are CVE-2026-53413 (buffer overflow), CVE-2026-53415 (use-after-free), and CVE-2026-53414 (missing bounds check causing denial-of-service), all affecting Zoom client applications before versions 7.1.5 and 7.0.6.
