nanoid (Nano ID) before 5.1.6 contains an infinite loop in the customAlphabet and customRandom functions. When these functions are configured with a size of 0, the internal generation loop never satisfies its exit condition and spins indefinitely, hanging the calling thread. An application that passes an unvalidated, attacker-controlled size of 0 to these functions is exposed to a denial-of-service condition.

———An issue was discovered in Samsung Exynos Mobile Processor, Automotive Processor, and Modem Exynos 9810, Exynos 9610, Exynos 9820, Exynos 980, Exynos 850, Exynos 1080, Exynos 2100, Exynos 2200, Exynos 1280, Exynos 1380, Exynos 1330, Exynos 9110, Exynos W920, Exynos Modem 5123, Exynos Modem 5300, an Exynos Auto T5123. In the Shannon SM Task, improper handling of a loop with an unreachable exit condition cannot guarantee the termination of a required service via a malformed SM message.1hCVE-2026-781327.5 HIG23.6%

——1zstd-jni versions 1.4.8-4 through 1.5.7-13 fail to validate negative length parameters in ZstdInputStreamNoFinalizer.read(), allowing attackers to trigger infinite loops. Attackers can pass negative length values to cause the read method to spin indefinitely while holding the stream monitor, blocking all other threads from accessing the stream.3dCVE-2026-880026.5 MED23.1%
——7Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.5.0 until 0.11.1, the message-chain reconstruction helper in backend/open_webui/utils/misc.py advanced through a chat history by map key but tracked visited entries using each message body's optional id field. An authenticated user could store id-less messages in a parent cycle and trigger a non-terminating walk that blocked the async event loop, grew memory until termination, and remained persistent across process restarts. This issue is fixed in version 0.11.1.4dCVE-2026-880006.5 MED23.1%
——7Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.10.0 until 0.11.1, DELETE /api/v1/chats/{id}/messages/{message_id} used the chat-history deletion helper in backend/open_webui/models/chats.py to follow childrenIds without recording visited message identifiers. An authenticated user could store a cyclic chat tree and delete a message, causing a synchronous infinite loop on the server request loop that blocked every user's requests until the process was killed. This issue is fixed in version 0.11.1.4d
