CNA source text (English)
Persistent client crash loop via undersized FLE2 insert-update ciphertext in decryption path
Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it, or able to control the responses the application receives, may cause that application to stop running.
