As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Catalyst SD-WAN engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-20313 are related to Improper link resolution before file access issues that are grouped under the Common Weakness Enumeration (CWE) CWE-1284.

CVE-2026-19026——
———H5Z__filter_nbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cd_values[0] through cd_values[4] without validating that cd_values is non-NULL or that cd_nelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the N-Bit filter pipeline message with zero client-data values, opened and read via H5Dread, e.g. by the h5ls or h5repack tools.7hCVE-2026-713147.5 HIG—
———Nuxt is an open-source web development framework for Vue.js. From 3.1.0 until 3.21.10 and 4.5.1, an unauthenticated attacker can use a server island v-for prop, including vforToArray and , to trigger unbounded SSR memory allocation until MAX_VFOR_LENGTH = 100000 and crash the Nuxt process. This issue is fixed in 3.21.10 and 4.5.1.9hCVE-2026-703787.5 HIG—
——0imagecli's `carve <ratio>` pipeline operation (Carve::apply() in src/image_ops.rs) only asserts `ratio <= 1.0`, never validating that the ratio is positive. A negative ratio (e.g. -5) causes the computed target width to saturate to 0 via Rust's defined float-to-uint cast, which is then passed to imageproc::seam_carving::shrink_width — a function that panics when given a width below 2, crashing the process. This shares the same missing-input-validation root cause as the sibling `scale` finding in the same file but is an independently fixable, distinct code path.16hCVE-2026-402727.0 HIG1.6%
——0Improper Input Validation in the decode() function of the traceparser library could allow an attacker with a corrupted kernel trace event log (.kev) file, to execute arbitrary code or cause a crash in processes that use libtraceparser in QNX hosts or targets.7dCVE-2026-54890—24.3%
——7Integer Underflow (Wrap or Wraparound) vulnerability in erlang otp erlang/otp (erts modules), erlang otp erts (erts modules) allows Forced Integer Overflow, Excessive Allocation. This vulnerability is associated with program files erts/emulator/beam/external.c, emulator/beam/external.c.
The BIT_BINARY_EXT tag (77) handler in the External Term Format (ETF) decoder accepts an encoding with both length and trailing-bits fields set to zero. The subsequent computation of the bitstring size underflows an unsigned integer, producing a value of roughly 2^64 that is then passed as a memory allocation size. The allocator aborts the entire node with a message such as "Cannot allocate 2305843009213693951 bytes of memory (of type binary)".
The crash is a VM-level abort, not an Erlang-level exception. It cannot be intercepted by supervision trees, by try/catch, or by passing the [safe] option to binary_to_term/2 (which only restricts atom creation and does not perform structural validation of binary encodings).
Any application that decodes ETF from untrusted sources via binary_to_term/1,2 or enif_binary_to_term() is exposed. The Erlang distribution protocol also decodes incoming terms through the same code path, but distribution is expected to run on trusted networks per the OTP Secure Coding Guidelines (DSG-011).
This issue affects OTP from OTP 27.0 before OTP 29.0.4, OTP 28.5.0.4 and OTP 27.3.4.15, corresponding to erts from 15.0 before 17.0.4, 16.4.0.4 and 15.2.7.11.7dCVE-2026-595327.5 HIG17.5%
