It appears that in response to the vulnerability (CVE-2023-4863) that affected Chrome but was caused by libwebp, Facebook has limited the uploading of webp files.<p>The recent "Chrome vulnerability" itself was actually a vulnerability in libwebp -- library used to manipulate webp files.<p>Now, when attempting to send a large webp file through messenger, I am greeted with the error:<p><pre><code> Unable to Add Attachment
Your image couldn't be uploaded due to restrictions on image dimensions. Image should be less than 2048 pixels in any dimension.
</code></pre>
I can only imagine this is some defence for their image compression systems which are possibly using the vulnerable libwebp library.<p>Facebook definitely isn't alone in this, and other services which compress or otherwise manipulate webp files are going to be affected by this too.
When searching HN about any posts on issues in libwebp nothing comes up.<p>Please do not assume that everyone has the same context as you when it comes to the subject matter that you start a thread on.<p>Preferably include a link to a source where the issues mentioned are listed/discussed.
