PamStealer Uses Fake Maccy Sites and PAM Checks to Steal Mac Login Passwords

Cybersecurity researchers have flagged a new macOS information stealer called PamStealer that employs a series of clever tricks to infect systems and siphon sensitive data. The stealer, discovered by Jamf Threat Labs, is distributed as a compiled AppleScript .scpt file impersonating Maccy, a...

DEBIAN-CVE-2026-12610

A flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of servi...

EUVD-2026-39386

Improper input validation in the PAM AD discovery endpoints in Devolutions Server 2026.2.4.0 through 2026.2.7.0 allows an authenticated user with the UserGroupsView permission to coerce server-side authentication to an attacker-controlled host, exposing PAM provider credentials as a NTLMv2...

CVE-2026-12755

CVE-2026-12755 affects Devolutions Server 2026.2.4.0–2026.2.7.0. It is caused by improper input validation in the PAM AD discovery endpoints. An authenticated user with the UserGroupsView permission can coerce server-side authentication to an attacker-controlled host, exposing PAM provider creden...

Zoho ManageEngine - Remote Code Execution

Zoho ManageEngine Password Manager Pro, PAM 360, and Access Manager Plus are susceptible to unauthenticated remote code execution via XML-RPC. An attacker can execute malware, obtain sensitive information, modify data, and/or gain full control over a compromised system without entering necessary...

CVE-2026-48981

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, pamusb calls xmlReadFile with flags=0 when loading the configuration file, allowing libxml2 to process external entity references XXE, potentially making outbound network connections or...

CVE-2026-48982

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

CVE-2026-48980 pam_usb: getenv() used in PAM context allows environment variable injection into local-check logic

pamusb provides hardware authentication for Linux using removable media. In versions prior to 0.9.2, getenv environment variables XRDPSESSION, DISPLAY and TMUX allow environment variable injection into local-check logic. These environment variables influence whether a current session is local or...

CVE-2026-48983 pam_usb: TOCTOU race condition in pad directory creation allows symlink substitution

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, a symlink race condition exists in per-device and per-user pad directory creation. pamusb uses a check-then-act pattern: it calls lstat to test for existence and then calls mkdir separate...

CVE-2026-48982 pam_usb: Missing O_EXCL on pad temp file creation allows concurrent update race

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

CVE-2026-48981 pam_usb: xmlReadFile flags=0 permits XXE network entity fetching in conf.c

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, pamusb calls xmlReadFile with flags=0 when loading the configuration file, allowing libxml2 to process external entity references XXE, potentially making outbound network connections or...

CVE-2026-48985

pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, pusbisloginctllocal can cause a NULL dereference crash when parsing loginctl output. The function calls popen and reads the result; if the Remote field is only a newline, fgets succeeds...

CVE-2026-48985 pam_usb: NULL Dereference Crash in pusb_is_loginctl_local when loginctl Returns Empty Remote Field
