t-digest versions 3.1 through 3.3 contain a denial of service vulnerability in MergingDigest.fromBytes that fails to validate length and capacity fields from serialized data. Attackers can supply crafted serialized digests with mismatched header fields to trigger ArrayIndexOutOfBoundsException or NegativeArraySizeException, aborting the parsing thread.

——1An issue was discovered in the mirage-crypto-pk package before 2.3.0 for OCaml. There is an undocumented exception for a small message during RSA decryption or encryption.2dCVE-2026-874709.6 CRÍ22.2%
——7Improper quantity validation in Tint in Google Chrome on on Mac prior to 153.0.8010.36 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Medium)1dCVE-2026-160257.5 ALT25.2%
——8Improper validation of specified quantity in input vulnerability in PayTR Payment and Electronic Money Institution Inc. PayTR Virtual Pos iFrame API (v9x) WHMCS Module allows Input Data Manipulation.
This issue affects PayTR Virtual Pos iFrame API (v9x) WHMCS Module: from v9.0.0 before v9.0.3.2dCVE-2026-793768.8 ALT13.4%
——4An issue in the l2cap_handle_data() function of Bestechnic Co., Ltd BES2300 Bluetooth Audio SoC firmware v3.x and earlier allows attackers to cause a Denial of Service (DoS) via sending a crafted L2CAP packet.2dCVE-2026-85201—1.5%
——0In Eclipse Ankaios versions 0.1.0 through 1.0.1, the agent does not limit the length declared by a workload in a length-delimited protobuf message received through the Control Interface FIFO. A workload granted Control Interface access can specify an excessive message length, causing an unbounded memory allocation that may abort the Ankaios agent process. This results in loss of orchestration services for workloads managed by the affected agent.3dCVE-2026-82751—25.8%
——8Improper Validation of Specified Quantity in Input in ZenHive mpp allows an unauthenticated remote client to inflate the fee-payer's gas cost per sponsored payment by a large multiplier and to have the sponsor pay for provisioning an access key on the client's own account.
When the server sponsors Tempo payments, MPP.Methods.Tempo.FeePayerPolicy.measure/3 in lib/mpp/methods/tempo/fee_payer_policy.ex bounds the gas fields, the fee budget, the validity window and the access list of the client-signed 0x76 envelope, but does not check whether the envelope carries the optional key_authorization field. A client can attach a fully signed key authorization, provisioning a new access key with token spending limits on its own account, alongside the normal payment call. The key and each limit entry are persistent storage writes billed as intrinsic gas to the sponsor, bounded only by the gas_limit ceiling. At the reporter's default of one key with three token limits the sponsored cost rises from about 46,587 gas to about 1,808,700 gas, and the client keeps a valid access key it paid nothing for.
This issue affects mpp: from 0.2.0 before 0.16.1.2d
