EUVDB-ID: #VU67413
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of user-supplied input within the fts5UnicodeTokenize() function in ext/fts5/fts5_tokenize.c, which caused the unicode61 tokenizer configured to treat unicode "control-characters" (class Cc), was treating embedded nul characters as tokens. A remote attacker can pass specially crafted input to the application and bypass implemented security restrictions.
