ImageMagick before 7.1.2-30 contains a time-of-check-time-of-use vulnerability in path policy enforcement on Windows that allows attackers to bypass read or write restrictions by exploiting symlink race conditions. Attackers can swap symlinks between policy validation and file access to read or write policy-denied files.

CVE-2026-864695.3 MED—
———A flaw was found in GLib2. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION and creating the .goutputstream-XXXXXX temporary file fails, the library unlinks the destination and recreates it without exclusive creation or symlink protection. A local attacker who can write to the destination directory can win that race and redirect the write to another file.6hCVE-2026-864242.5 BAJ—
———ImageMagick before 7.1.2-30 and 6.9.13-55 contains a time-of-check-time-of-use (TOCTOU) vulnerability in the video decoder that allows attackers to bypass path policy write restrictions via symlink swaps. An attacker can replace a symlink between policy validation (check-time) and the file write operation (use-time) to write to policy-denied locations.9hCVE-2026-855836.5 MED39.5%
——12SiYuan versions before v3.8.2 contain a path traversal vulnerability in the reader-accessible file-read endpoint that follows symlinks when opening authorized asset paths. Attackers with reader role can request a logical asset under data/assets/ that is a symlink to a file outside the workspace and receive the target file bytes, bypassing workspace boundary restrictions.3dCVE-2026-850926.6 MED4.7%
——1LiME through 1.12.0 fails to validate the disk acquisition output path and does not use O_NOFOLLOW when opening the operator-supplied path parameter, allowing unprivileged local users to overwrite arbitrary root-owned files. An attacker who controls the output directory can create a symbolic link with the expected filename pointing to any root-owned file, and when the acquisition runs in kernel context, LiME follows the link and truncates the target file with the memory acquisition stream.4dCVE-2026-784097.0 ALT2.4%
——1The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to open_tree() with AT_SYMLINK_NOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with an fstab-authorized X-mount.subdir entry can attach a host path at the intended mountpoint.4dCVE-2024-140477.2 ALT0.9%
——0A local vulnerability in the Winlogbeat Windows installer caused runtime files to be placed in a directory writable by unprivileged users. A low-privileged attacker with existing access to the system could pre-position malicious filesystem links, causing a subsequent elevated Winlogbeat operation to write to or delete arbitrary files. Successful exploitation could result in a denial of service.6d
