GHSA-44qr-rrjg-2cqq: @apostrophecms/form (CVE-2026-113667)

Package	Ecosystem	Affected	Fixed in
@apostrophecms/form	npm	<1.5.5	1.5.5
@apostrophecms/login-recaptcha	npm	<1.2.1	1.2.1
@apostrophecms/login-hcaptcha	npm	<1.3.0	1.3.0

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The @apostrophecms/form package before 1.5.5, @apostrophecms/login-hcaptcha before 1.3.0, and @apostrophecms/login-recaptcha before 1.2.1 build their CAPTCHA verification requests by inserting the user-supplied token without URL encoding. The source says an attacker can submit a crafted token that adds extra parameters to the outbound verification request, which may cause verification failures and help probe for bypasses, though it reports no secret exfiltration. Upgrade @apostrophecms/form to 1.5.5, @apostrophecms/login-hcaptcha to 1.3.0, and @apostrophecms/login-recaptcha to 1.2.1 or later.
