+# Haskell Security Response Team - 2024 April–June report
+
+The Haskell Security Response Team (SRT) is a volunteer organization
+within the Haskell Foundation that is building tools and processes
+to aid the entire Haskell ecosystem in assessing and responding to
+security risks.  In particular, we maintain a [database][repo] of
+security advisories that can serve as a data source for security
+tooling.
+
+This report details the SRT activities from April through June
+2024.
+
+The SRT is:
+
+- Casey Mattingly
+- Fraser Tweedale
+- Gautier Di Folco
+- Mihai Maruseac
+- Tristan de Cacqueray
+
+[repo]: https://github.com/haskell/security-advisories
+
+
+## How to contact the SRT
+
+For assistance in coordinating a security response to newly
+discovered, high impact vulnerabilities, contact
+`security-advisories@haskell.org`.  Due to limited resources, we can
+only coordinate embargoed disclosures for high impact
+vulnerabilities affecting current versions of core Haskell tools and
+libraries, or in other exceptional cases.
+
+You can submit lower-impact or historical vulnerabilities to the
+advisory database via a pull request to our [GitHub
+repository][repo].
+
+You can also contact the SRT about non-advisory/security-response
+topics.  We prefer public communication where possible.  In most
+cases, [GitHub issues][gh-new-issue] are an appropriate forum.  But
+the mail address is there if no other appropriate channel exists.
+

+
+
+## Growing the SRT
+
+Following discussions at the 2024 Haskell Ecosystem Workshop, we
+have decided to grow the SRT.  This is in recognition of the
+expanding scope of the SRT's work.  For example, we would like to
+improve security tooling for Haskell developers, but we are limited
+by our volunteer members' capacity.  There are several high-impact
+projects awaiting attention.  Growing the team will enable us to
+address more of these, while (hopefully) reserving some capacity to
+address urgent security issues when they arise.
+
+Additionally, Casey Mattingly has decided to retire from the SRT.
+Casey, thank you for your significant contributions during the SRT's
+first year.
+
+The SRT will put out a new Call for Volunteers soon.  Keep an eye
+out for it, and we look forward to welcoming new members soon!
+
+
+## Advisory database
+
+1 contemporary advisory was published during the reporting period.
+
+0 historical advisories were added during the reporting period.
+
+2 HSEC IDs (HSEC-2024-0004 and HSEC-2024-0005) have been reserved
+for embargoed vulnerabilities, which will be published later.
+
+We urge community members to submit to the database any known
+security issues, including historical issues, that are not yet
+included.
+
+
+## SRT at the Haskell Ecosystem Workshop and ZuriHac 2024
+
+In early June, Gautier and Fraser attended the [Haskell Ecosystem
+Workshop] and [ZuriHac], co-located at OST Rapperswil near Zürich.
+Fraser presented ([slides]) at the Workshop, giving an overview of
+the SRT's processes, work, tooling, and future evolution.

+[slides]: https://speakerdeck.com/frasertweedale/haskell-security-response-team-haskell-ecosystem-workshop-2024
+
+There were many highlights from 5 days of collaboration across both
+events:
+
+- New security issues were reported, and SRT initiated a response.
+- New contributors made valuable contributions:
+  - André Espaze implemented a [*Security* page][haskell.org-security]
+    for the `www.haskell.org` website ([pull request][pr-300]).
+  - andrii (`@unorsk`) took up the work of implementing CVSS 4.0
+    support for the advisory database.
+
+- Gautier improved the HTML advisory index generation
+- Mango (`@MangoIV`) continued work on [cabal-audit] and
+  bugfixes/improvements to the advisory libraries.
+- Mango also started work on SPDX SBOM generation.
+- SRT members gave security advice to other projects.
+- Many people shared ideas about the evolution and strengthening of
+  the SRT, and the Haskell security posture more generally.

+
+Fraser especially thanks the Haskell Foundation for travel
+assistance (Zürich is a long way from Australia!)
+
+
+## Reporting vulnerabilities via VINCE
+
+The CERT/CC [VINCE] system supports confidential reporting of
+vulnerabilities and response coordination.  The Haskell ecosystem is
+now represented in VINCE as the *"Haskell Programming Language"*
+vendor.
+
+VINCE is especially valuable for coordinated security response and
+disclosure of vulnerabilities that impact multiple ecosystems.  For
+example, [HSEC-2024-0003] impacted many languages, including Rust,
+PHP, Node.js and Erlang.  Representatives of the affected ecosystems
+shared information, including mitigation techniques, and prepared
+for coordinated disclosure and fix releases.
+
+Although anyone can use VINCE to report a vulnerability to the SRT,
+we encourage its use only for **high-impact vulnerabilities** and
+**vulnerabilities that impact multiple ecosystems** or vendors.  For
+low-severity issues that only impact the Haskell ecosystem, please
+follow the process in the [Reporting Vulnerabilities][reporting]
+document.

+
+## Security guides
+
+The SRT from time to time will publish "security best practices"
+guides on particular topics, tailored to users of Haskell.  Mihai
+published the first of these in May: [How to secure GitHub
+repositories][guide-github].  Thanks Mihai!
+
+What other security guides would be helpful for the Haskell
+community?  Please let us know via email or GitHub issue.

+
+## SRT libraries and tools on Hackage
+
+We have published the following libraries and tools on
+`hackage.haskell.org`:
+
+- [***cvss***](https://hackage.haskell.org/package/cvss):
+  types and functions for the [*Common Vulnerability Scoring System*][cvss]
+- [***osv***](https://hackage.haskell.org/package/osv):
+  the [*Open Source Vulnerabilities (OSV) schema*][osv-schema]
+- [***hsec-core***](https://hackage.haskell.org/package/hsec-core):
+  our core advisory type
+- [***hsec-tools***](https://hackage.haskell.org/package/hsec-tools):
+  advisory parsing and processing (library), *and* the `hsec-tools`
+  executable for managing the advisory database and export
+  artifacts
+- [***hsec-sync***](https://hackage.haskell.org/package/hsec-sync):
+  executable for downloading and synchronising *snapshots* of the
+  advisory database content, intended for Haskell ecosystem tooling
+
+[cvss]: https://en.wikipedia.org/wiki/Common_Vulnerability_Scoring_System
+[osv-schema]: https://ossf.github.io/osv-schema/
+
+We will also publish a [*Common Weakness Enumeration (CWE)*][cwe]
+library, which is still in development.
+
+[cwe]: https://cwe.mitre.org/
+
+
+## Tooling updates
+
+- Gautier implemented advisory snapshots.  These are intended for
+  distribution and consumption by downstream tools (so they don't
+  have to clone the whole *security-advisories* Git repo).
+- Gautier enhanced the style and content of our HTML advisory index
+  generator.
+- Mango fixed several bugs in *hsec-core* and purged `ZonedTime`
+  from the codebase.  The `Advisory` type now uses `UTCTime`.
+- Tristan is adding support for the `GHC` advisory namespace, which
+  is already defined in the OSV schema.  It is for advisories
+  affecting the compiler or other tools that can not be properly
+  identified in the `Hackage` namespace.
+- Early in Q3 we will publish new versions of most of our packages,
+  incorporating the changes mentioned above (and more).
