Security fixes

This release contains two low severity security fixes:

  • GHSA-gmgw-rcmh-7x47 reports potential cross-site side-effects due to not applying sandboxing to iframes.

  • Switch from deprecated shortid to nanoid module, with 10 character long aliases in “public” links

Security fixes

This release fixes a security issue of a possible XSS exploit which can be planted via a malicous SVG file upload.

See CVE-2025-32391 for more details

Enhancements

  • Add config options CMD_SAML_WANT_ASSERTIONS_SIGNED and CMD_SAML_WANT_AUTHN_RESPONSE_SIGNED for SAML auth, since some instances didn’t comply with the new defaults of @node-saml/passport-saml

HedgeDoc 1.10.2

 Released on
Click here to read the release notes

PLEASE CHECK THIS IF YOU USE SAML AUTHENTICATION: This release had to set default values for the username and email address attribute mapping for SAML authentication for security reasons. If you use SAML authentication, please make sure to update your SAML configuration accordingly. See: https://docs.hedgedoc.org/configuration/#saml-login CMD_SAML_ATTRIBUTE_USERNAME or CMD_SAML_ATTRIBUTE_EMAIL

Bugfixes

  • Check if a valid user id is present when using OAuth2
  • Abort SAML login if NameID is undefined instead of logging in with a user named “undefined” (Thanks @Haanifee)
  • Set default values for username and email attribute mapping in SAML configuration

HedgeDoc 1.10.1

 Released on
Click here to read the release notes

This release fixes a security issue where brute-forcing local email/passwords is possible because of missing rate-limits. We recommend upgrading as soon as possible, if you use local logins.

See also https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-6w39-x2c6-6mpf

This release changes the default configuration of the HSTS preload attribute to false for compliance with the HSTS preload list requirements. This shouldn’t impact any instance. However, if you intend to use HSTS preloading you should enable the config setting hsts.preload to true or set environment variable CMD_HSTS_PRELOAD=true.

This release deprecates support for Node 18. As the LTS support for 18 runs out in April 2025, the next release will only work with Node 20 and upwards. Consider this your early warning to upgrade any running instances to at least Node 20.

Enhancements

  • Add fixed rate-limiting to the login and register endpoints
  • Add configurable rate-limiting to the new notes endpoint

Bugfixes

  • Fix a crash when cannot read user profile in OAuth (#5850 by @lautaroalvarez)
  • Fix CSP Header for mermaid embedded images (#5887 by @domrim)
  • Change default of HSTS preload to false for compliance with the HSTS preload list requirements (#5913 by @SvizelPritula)

HedgeDoc 1.9.0

 Released on
Click here to read the release notes

Security Fixes

  • CVE-2021-39175: XSS vector in slide mode speaker-view
  • This release removes Google Analytics and Disqus domains from our default Content Security Policy, because they were repeatedly used to exploit security vulnerabilities.
    If you want to continue using Google Analytics or Disqus, you can re-enable them in the config. See the docs for details

Features

  • HedgeDoc now automatically retries connecting to the database up to 30 times on startup
  • This release introduces the csp.allowFraming config option, which controls whether embedding a HedgeDoc instance in other webpages is allowed. We strongly recommend disabling this option to reduce the risk of XSS attacks
  • This release introduces the csp.allowPDFEmbed config option, which controls whether embedding PDFs inside HedgeDoc notes is allowed. We recommend disabling this option if you don’t use the feature, to reduce the attack surface of XSS attacks
  • Add additional environment variables to configure the database. This allows easier configuration in containerized environments, such as Kubernetes

Enhancements

  • Further improvements to the frontend build process, reducing the initial bundle size by 60%
  • Improve the error handling of the filesystem upload method
  • Improve the error message of failing migrations

Bugfixes

Miscellaneous

HedgeDoc 1.8.1
