✅ php2shell is fixed – Citrix updated CTX697263 today: 14.1-73.49 · 13.1-64.32 · 14.1-73.49 FIPS · 13.1-37.286 FIPS/NDcPP.
They also contain the CTX697096, CVE-2026-88779 and CVE-2026-107406 fixes, so one upgrade covers everything.
• ICA/VPN sessions drop during the upgrade – plan a window
• samlRejectUnsignedAssertion OFF is forced ON
• Keep the management GUI restricted with ACLs (CTX228148), before and after
Checker v1.18 is out: php2shell status by build, and on an unfixed build an open management GUI is now VULNERABLE (exit code 2 – heads-up if you run it from Console jobs or scripts).

Sure about the ICA/VPN sessions being dropped? Just upgraded the first HA pair and just had the regular small 'network-hick-up'. So no reconnection needed.

your correct, also had this previous build, they said it would be the new way of patching but it jumps a build or two

The ICA proxy session-ticket behaviour introduced in 73.37 and 64.24 still applies. If you’re jumping from an older build, users reconnecting with tickets issued before the upgrade will have to restart their sessions. / 50/50 flip of the coin now
