[](https://renovatebot.com) This PR contains the following updates: | Package | Change | Age | Adoption | Passing | Confidence | |---|---|---|---|---|---| | [hono](https://hono.dev/) ([source](https://togithub.com/honojs/hono)) | [`4.5.5` -> `4.5.8`](https://renovatebot.com/diffs/npm/hono/4.5.5/4.5.8) | [](https://docs.renovatebot.com/merge-confidence/) | [](https://docs.renovatebot.com/merge-confidence/) | [](https://docs.renovatebot.com/merge-confidence/) | [](https://docs.renovatebot.com/merge-confidence/) | ### GitHub Vulnerability Alerts #### [CVE-2024-43787](https://togithub.com/honojs/hono/security/advisories/GHSA-rpfr-3m35-5vx5) ### Summary Hono CSRF middleware can be bypassed using crafted Content-Type header. ### Details MIME types are case insensitive, but `isRequestedByFormElementRe` only matches lower-case. https://github.com/honojs/hono/blob/b0af71fbcc6dbe44140ea76f16d68dfdb32a99a0/src/middleware/csrf/index.ts#L16-L17 As a result, attacker can bypass csrf middleware using upper-case form-like MIME type, such as "Application/x-www-form-urlencoded". ### PoC ```html <html> <head> <title>CSRF Test</title> <script defer> document.addEventListener("DOMContentLoaded", () => { document.getElementById("btn").addEventListener("click", async () => { const res = await fetch("http://victim.example.com/test", { method: "POST", credentials: "include", headers: { "Content-Type": "Application/x-www-form-urlencoded", }, }); }); }); </script> </head> <body> <h1>CSRF Test</h1> <button id="btn">Click me!</button> </body> </html> ``` ### Impact Bypass csrf protection implemented with hono csrf middleware. ### Discussion I'm not sure that omitting csrf checks for Simple POST request is a good idea. CSRF prevention and CORS are different concepts even though CORS can prevent CSRF in some cases. --- ### Release Notes <details> <summary>honojs/hono (hono)</summary> ### [`v4.5.8`](https://togithub.com/honojs/hono/releases/tag/v4.5.8) [Compare Source](https://togithub.com/honojs/hono/compare/v4.5.7...v4.5.8) ##### Security Fix for CSRF Protection Middleware Before this release, in versions 4.5.7 and below, the CSRF Protection Middleware did not treat requests including `Content-Types` with uppercase letters (e.g., `Application/x-www-form-urlencoded`) as potential attacks, allowing them to pass. This could cause unexpected behavior, leading to a vulnerability. If you are using the CSRF Protection Middleware, please upgrade to version 4.5.8 or higher immediately. For more details, see the report here: GHSA-rpfr-3m35-5vx5 ### [`v4.5.7`](https://togithub.com/honojs/hono/releases/tag/v4.5.7) [Compare Source](https://togithub.com/honojs/hono/compare/v4.5.6...v4.5.7) #### What's Changed - fix(jsx/dom): Fixed a bug that caused Script elements to turn into Style elements. by [@​usualoma](https://togithub.com/usualoma) in [https://github.com/honojs/hono/pull/3294](https://togithub.com/honojs/hono/pull/3294) - perf(jsx/dom): improve performance by [@​usualoma](https://togithub.com/usualoma) in [https://github.com/honojs/hono/pull/3288](https://togithub.com/honojs/hono/pull/3288) - feat(jsx): improve a-tag types with well known values by [@​ssssota](https://togithub.com/ssssota) in [https://github.com/honojs/hono/pull/3287](https://togithub.com/honojs/hono/pull/3287) - fix(validator): Fixed a bug in hono/validator where URL Encoded Data could not be validated if the Content-Type included charset. by [@​uttk](https://togithub.com/uttk) in [https://github.com/honojs/hono/pull/3297](https://togithub.com/honojs/hono/pull/3297) - feat(jsx): improve `target` and `formtarget` attribute types by [@​ssssota](https://togithub.com/ssssota) in [https://github.com/honojs/hono/pull/3299](https://togithub.com/honojs/hono/pull/3299) - docs(README): change Twitter to X by [@​nakasyou](https://togithub.com/nakasyou) in [https://github.com/honojs/hono/pull/3301](https://togithub.com/honojs/hono/pull/3301) - fix(client): replace optional params to url correctly by [@​yusukebe](https://togithub.com/yusukebe) in [https://github.com/honojs/hono/pull/3304](https://togithub.com/honojs/hono/pull/3304) - feat(jsx): improve input attribute types based on react by [@​ssssota](https://togithub.com/ssssota) in [https://github.com/honojs/hono/pull/3302](https://togithub.com/honojs/hono/pull/3302) #### New Contributors - [@​uttk](https://togithub.com/uttk) made their first contribution in [https://github.com/honojs/hono/pull/3297](https://togithub.com/honojs/hono/pull/3297) **Full Changelog**: honojs/hono@v4.5.6...v4.5.7 ### [`v4.5.6`](https://togithub.com/honojs/hono/releases/tag/v4.5.6) [Compare Source](https://togithub.com/honojs/hono/compare/v4.5.5...v4.5.6) #### What's Changed - fix(jsx): handle async component error explicitly and throw the error in the response by [@​usualoma](https://togithub.com/usualoma) in [https://github.com/honojs/hono/pull/3274](https://togithub.com/honojs/hono/pull/3274) - fix(validator): support multipart headers without a separating space by [@​Ernxst](https://togithub.com/Ernxst) in [https://github.com/honojs/hono/pull/3286](https://togithub.com/honojs/hono/pull/3286) - fix(validator): Allow form data will mutliple values appended by [@​nicksrandall](https://togithub.com/nicksrandall) in [https://github.com/honojs/hono/pull/3273](https://togithub.com/honojs/hono/pull/3273) - feat(jsx): improve meta-tag types with well known values by [@​ssssota](https://togithub.com/ssssota) in [https://github.com/honojs/hono/pull/3276](https://togithub.com/honojs/hono/pull/3276) #### New Contributors - [@​Ernxst](https://togithub.com/Ernxst) made their first contribution in [https://github.com/honojs/hono/pull/3286](https://togithub.com/honojs/hono/pull/3286) - [@​ssssota](https://togithub.com/ssssota) made their first contribution in [https://github.com/honojs/hono/pull/3276](https://togithub.com/honojs/hono/pull/3276) **Full Changelog**: honojs/hono@v4.5.5...v4.5.6 </details> --- ### Configuration 📅 **Schedule**: Branch creation - "" in timezone America/Chicago, Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
