CVE-2024-35333
HighSummary
W funkcji read_charset_decl w html2xhtml 1.3 występuje podatność typu przepełnienia bufora stosu. Problem ten wynika z niewłaściwego sprawdzania granic podczas kopiowania danych do bufora stosu o stałej wielkości.
Risk Assessment
Atakujący może wykorzystać tę podatność, dostarczając specjalnie przygotowane dane, co może prowadzić do wykonania dowolnego kodu, odmowy usługi lub uszkodzenia danych.
Recommendation
Zaleca się aktualizację do najnowszej wersji html2xhtml, aby usunąć tę podatność oraz wdrożenie odpowiednich mechanizmów zabezpieczających przed atakami typu buffer overflow.

P4 Search prior to 2026.4.2 does not fail securely when its service authentication token is blank. In affected configurations, an unauthenticated attacker with network access can obtain the highest application privilege, potentially leading to compromise of P4 Search and the connected P4 Server.
- CVE-2026-100103Critical
Perforce P4 Search container images prior to 2026.4.2 reset the service authentication token to a publicly documented default value. An unauthenticated attacker with network access can obtain the highest application privilege, potentially leading to arbitrary code execution and compromise of the connected P4 Server.
- CVE-2026-100102Critical
Perforce P4 Search container images prior to 2026.4.2 enable an unauthenticated Java debug interface. An attacker with network access to this interface can execute arbitrary code as the P4 Search service account, potentially leading to compromise of the connected P4 Server.

ZITADEL before 3.4.14 and 4.x before 4.16.2 contains an authentication bypass in the hosted Login V1 UI because the 'external account not found' registration endpoint trusts client-supplied external identity fields without a completed IdP callback. Unauthenticated attackers can submit forged IDPConfigID and ExternalUserID values to pre-create an account bound to a victim's external IdP identity, which the victim's later genuine external login then signs into.
- CVE-2026-105209Critical
ZITADEL 3.x before 3.4.15 and 4.x before 4.17.1 contains an improper authorization vulnerability: when issuing passkey or passwordless enrollment codes, it checks only the organization in the x-zitadel-orgid header, not the target user's organization. Attackers with user-write permission in one organization can obtain an enrollment code for a user in another organization on the same instance and register their own authenticator to take over that account.
- CVE-2026-105207Critical
ZITADEL 3.0.0 through 3.4.15 and 4.0.0 before 4.17.3 creates links between user accounts and external identity providers without verifying a primary factor or the caller's permission, including on identify-only Login V2 sessions and via the User Service V2 AddIDPLink endpoint. An unauthenticated attacker knowing a victim's login name can bind their own external IdP identity to the victim's account and then sign in as the victim.

A code injection vulnerability was found in InternLM MindSearch 0.1.0 in the ExecutionAction.run function in mindsearch/agent/graph.py. The attack can be launched remotely, and exploit details have been publicly disclosed.
Original NVD description (English source)
A stack-buffer-overflow vulnerability exists in the read_charset_decl function of html2xhtml 1.3. This vulnerability occurs due to improper bounds checking when copying data into a fixed-size stack buffer. An attacker can exploit this vulnerability by providing a specially crafted input to the vulnerable function, causing a buffer overflow and potentially leading to arbitrary code execution, denial of service, or data corruption.
