Four new members joined at Community Day Europe in Prague, alongside a CRA Readiness guide and role-based user journeys. Organizations contributed more than 1,400 dependency updates and security fixes upstream, as discussed in an upcoming Tech Talk featuring Ericsson, ActiveState, and Linux Foundation Research. A new Linux Foundation survey found AI cuts open source coding time in half, and 25% of incoming pull requests are considered 'AI slop.' Privateer, an AI-assisted compliance evaluation framework, joined the OpenSSF Sandbox. GitHub expanded malware advisories to eight ecosystems using OpenSSF data. Project releases include OpenBao v2.7.2, Sigstore Cosign v3.1.4, Rekor v1.5.5, and Zarf v0.88.0. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What percentage of open source pull requests are considered low quality AI-generated submissions? Maintainers estimate that 25% of incoming pull requests are considered 'AI slop,' according to new Linux Foundation research supported by OpenSSF. The same research found that generative AI cuts open source coding time roughly in half, but contributors still need to understand and test what they submit, per OpenSSF Chief of Staff Adrianne Marcum. _Developers weighing AI-assisted contributions against review overhead can track this kind of research on daily.dev._ ### What changed in Sigstore Cosign v3.1.4? Cosign v3.1.4 adds a bundle create-from-container command, builds releases with Go 1.27.3, and publishes community AI policy guidelines in AGENTS.md. Alongside it, Rekor released v1.5.5 with configurable TLS serving and JSON canonicalization improvements, and sigstore-python v4.5.1 and sigstore-java v2.4.0 received major dependency and verification upgrades. _Teams verifying software supply chains with Sigstore can follow release notes like these on daily.dev before upgrading._ ### How is GitHub expanding its malware advisory coverage for open source packages? GitHub integrated OpenSSF's malicious-package data into its Advisory Database, expanding Dependabot malware alerts across eight ecosystems. This case study shows how upstream security data feeds directly into GitHub's dependency scanning and alerting tools. _Developers relying on Dependabot alerts across ecosystems can keep up with coverage changes like this on daily.dev._ ## Similar posts on daily.dev - [OpenSSF Newsletter – May 2026 – Open Source Security Foundation](https://daily.dev/posts/openssf-newsletter-may-2026-open-source-security-foundation-envxbelwn) · OpenSSF · 0 upvotes · 0 comments - [OpenSSF Newsletter – September 2026 – Open Source Security Foundation](https://daily.dev/posts/openssf-newsletter-september-2026-open-source-security-foundation-po4487ovb) · OpenSSF · 0 upvotes · 0 comments - [OpenSSF Newsletter – July 2026 – Open Source Security Foundation](https://daily.dev/posts/openssf-newsletter-july-2026-open-source-security-foundation-pfg1vkjsr) · OpenSSF · 0 upvotes · 0 comments - [OpenSSF Announces New Members & AI Security Resources](https://daily.dev/posts/openssf-announces-new-members-ai-security-resources-dhtsiofbz) · OpenSSF · 0 upvotes · 0 comments - [This Week in Open Source for October 30, 2026](https://daily.dev/posts/this-week-in-open-source-for-october-30-2026-4hxesktg4) · Google Open Source Blog · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security) [View this post on daily.dev](https://daily.dev/posts/openssf-newsletter-october-2026-open-source-security-foundation-ly3binpyh) ```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":"OpenSSF Newsletter – October 2026 – Open Source Security Foundation","url":"https://daily.dev/posts/openssf-newsletter-october-2026-open-source-security-foundation-ly3binpyh","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openssf-newsletter-october-2026-open-source-security-foundation-ly3binpyh"},"datePublished":"2026-10-30T19:56:38.577Z","dateModified":"2026-10-30T19:57:08.679Z","description":"OpenSSF's October 2026 newsletter rounds up new members, CRA resources, and an AI vulnerability guide.
