📌 Stable versions on Packagist are now immutable. Once published, the commit a version points to can no longer change. Retags are blocked, and deleted versions are tracked with a reason and recoverable. blog.packagist.com/immutable-v... #php #phpc #composerphp

I had a chat with Jordi Boggiano from Packagist about a heap of security features they recently added and adding in the future The security of the public package repositories is a hot topic right now, Packagist is doing some really interesting things to improve their security

Busy times: Here are my slides on Composer & Packagist Supply Chain Security from #PHPVerse: naderman.de/slippy/slide... Thanks @jetbrains.com for a great online event! Videos soon! Follow blog.packagist.com for updates. #php #phpc #composerphp #supplychainsecurity

🧩 Composer plugins are powerful, but execute code during install & update. Composer prompts to allow a plugin, but a distracted "yes" or an AI agent on autopilot is all it takes. Private Packagist now has org-level allowlists for plugins. blog.packagist.com/restricting-... #php #phpc #composerphp

The Composer CLI is part of your supply chain. Older versions miss the protections from 2.10 and have known CVEs of their own. Private Packagist customers can now enforce which Composer versions are allowed to use their repository. blog.packagist.com/enforce-a-sa... #php #phpc #composerphp

Ever found yourself accidentally merging changes to the public API of a PHP package and regretting it later? I made a GitHub Action to help prevent that. seld.be/notes/surfac...

🛡️ Composer's download fallback behavior can silently override security decisions at the repository side, falling back from a blocked Private Packagist URL to GitHub or a source clone. Two new Private Packagist options close it off. blog.packagist.com/closing-comp... #php #phpc #composerphp

I realized I was never going to get to adding zizmor to all my repos so I made a claude skill to let it do the grunt work. You can use it too, if it helps more busy/lazy people to secure their GitHub repos I am glad! See github.com/Seldaek/zizm...

📦 Composer 2.10 is out. Native malware filtering via @aikidosecurity.bsky.social (enabled by default on Packagist), a unified config.policy framework for advisories/abandoned/malware, and source fallback now deprecated. blog.packagist.com/composer-2-1... #php #phpc #composerphp

🔒 An update on Composer & Packagist supply chain security: where we stand, what ships this week with Composer 2.10, what's next. If you maintain PHP packages, enable MFA now. blog.packagist.com/an-update-on... #php #phpc #composerphp #supplychainsecurity

It took us a bit longer than expected but after over a month of discussions and rewrites, Composer 2.10 RC2 is now available for testing with a new policy config and detected malware now blocked by default on install. github.com/composer/com... #composerphp #phpc

We recommend you change the default permissions for GitHub Actions GITHUB_TOKENs to read only. Explicitly grant elevated permissions only where strictly necessary. Use zizmor to analyze your GitHub Actions: github.com/zizmorcore/z... see also: phpunit.expert/articles/har...

If you haven't updated Composer to 2.9.8 or 2.2.28 (LTS), do so urgently! GitHub will restart the rollout of their new GitHub Actions tokens later today. They've improved secret masking to cover this Composer issue, but you're safer if you update. #composerphp #php #phpc

Three-month Private Packagist recap: malware filter list support is already in place, ahead of Composer 2.10's release next week. Plus a new permissions tab, better job visibility, and narrower GitLab OAuth scopes. blog.packagist.com/whats-new-in... #php #phpc #composerphp

UPDATE: GitHub has rolled back their change to GitHub Actions tokens, no longer necessary to immediately disable GitHub Actions. We now have a few days to get the PHP ecosystem updated to safe Composer versions, before a new rollout of the new token format is attempted. #php #composerphp #phpc

🚨 Security advisory: Composer 2.9.8 and 2.2.28 fix a vulnerability leaking GitHub Actions GITHUB_TOKENs to job logs via error messages. Update now or disable affected workflows. blog.packagist.com/composer-2-9... #composerphp #phpc #php

Packagist needs to finance staff, not just hardware and bandwidth. Contact me if your company's interested in joining our sponsorship program for its launch this month while we work on long term solutions.

Open infrastructure isn't free. 🌱 Packagist/Composer signed a joint @openssf.org letter with PyPI, crates, Maven, CPAN, etc on real cost of running package registries. #php #phpc #composerphp #softwaresupplychain #PreserveOpenSource #FreeSoftwareIsntFree #OpenSource #Sustainability

🚨 Composer 2.9.6 and 2.2.27 are out with fixes for CVE-2026-40261 and CVE-2026-40176, command injection issues in the Perforce driver. Run composer self-update now. No exploits detected on Packagist.org and Private Packagist. Details: blog.packagist.com/composer-2-9... #php #phpc #composerphp

New in Private Packagist: Usage Tracking can now help prioritize security updates by showing how deps cascade through projects and where vulnerable versions are used. Trusted Publishing for GitHub Actions and better synchronization setup. blog.packagist.com/whats-new-in... #php #phpc #composerphp

After Composer 2.9 CLI security improvements, we're working on a transparency log for Packagist to strengthen PHP supply chain security, funded by the @sovereign.tech with help of the @thephpf.bsky.social and Private Packagist. Details at blog.packagist.com/strengthenin... #php #phpc #composerphp

Composer 2.9 is here! 🚀 It automatically blocks packages with known vulnerabilities, has a new repository command to manage repos from the CLI, and lots more! blog.packagist.com/composer-2-9/ #composerphp #phpc #PHP

Composer 2.9 is coming, and there's an RC to try out! We need your help and feedback github.com/composer/com... #composerphp #phpc

🚨 Warning to #PHP package maintainers: We did not email you to change your passwords & 2FA. Emails asking you to update your credentials are a phishing attempt. We had the phishing site & domain taken down. If you got the email and entered your credentials, please contact us. #phpc

Together with PyPI, Maven Central, cratesio and other major package registries we signed a statement on sustainable open source infrastructure. 3B+ installs/month and evolving #composerphp and packagist.org requires sharing the costs. #phpc #php
