Video ThePrimeTime · 21w Vim Has A 0-Day???? Claude AI discovered a remote code execution (RCE) vulnerability in Vim triggered by Vim's modeline feature, which allows files to embed and auto-execute editor commands on open. The exploit chains modeline commands to set up a tab panel expression that registers an autocommand, ultimately executing arbitrary shell commands when a malicious file is opened. A second vulnerability attributed to Emacs is also covered, but the author argues it's actually a Git fsmonitor config exploit — not an Emacs bug — that executes arbitrary scripts whenever git status is run inside a maliciously crafted repository. The author praises the Vim find as genuinely clever while criticizing the Emacs report as a misattributed bug that wastes maintainer time, drawing parallels to similar issues with cURL's HackerOne program. 104 5 [See all Vim archives](/tags/vim/best-of) ```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","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/tags/vim/best-of/2026/04#page","url":"https://daily.dev/tags/vim/best-of/2026/04","name":"Best Vim Posts — April 2026","description":"The most upvoted Vim posts from April 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/tags/vim/best-of/2026/04#items","numberOfItems":1,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/vim-has-a-0-day--4gcvjxjv9","name":"Vim Has A 0-Day????"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Tags","item":"https://daily.dev/tags"},{"@type":"ListItem","position":3,"name":"Vim","item":"https://daily.dev/tags/vim"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/tags/vim/best-of"},{"@type":"ListItem","position":5,"name":"April 2026"}]}]} ```
