CVE-2026-34520 1 Aio-libs 1 Aiohttp 2026-04-04 9.1 Critical
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, the C parser (the default for most installs) accepted null bytes and control characters in response headers. This issue has been patched in version 3.13.4.
CVE-2026-23333 1 Linux 1 Linux Kernel 2026-04-03 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_rbtree: validate open interval overlap Open intervals do not have an end element, in particular an open interval at the end of the set is hard to validate because of it is lacking the end element, and interval validation relies on such end element to perform the checks. This patch adds a new flag field to struct nft_set_elem, this is not an issue because this is a temporary object that is allocated in the stack from the insert/deactivate path. This flag field is used to specify that this is the last element in this add/delete command. The last flag is used, in combination with the start element cookie, to check if there is a partial overlap, eg. Already exists: 255.255.255.0-255.255.255.254 Add interval: 255.255.255.0-255.255.255.255 ~~~~~~~~~~~~~ start element overlap Basically, the idea is to check for an existing end element in the set if there is an overlap with an existing start element. However, the last open interval can come in any position in the add command, the corner case can get a bit more complicated: Already exists: 255.255.255.0-255.255.255.254 Add intervals: 255.255.255.0-255.255.255.255,255.255.255.0-255.255.255.254 ~~~~~~~~~~~~~ start element overlap To catch this overlap, annotate that the new start element is a possible overlap, then report the overlap if the next element is another start element that confirms that previous element in an open interval at the end of the set. For deletions, do not update the start cookie when deleting an open interval, otherwise this can trigger spurious EEXIST when adding new elements. Unfortunately, there is no NFT_SET_ELEM_INTERVAL_OPEN flag which would make easier to detect open interval overlaps.
CVE-2026-23448 1 Linux 1 Linux Kernel 2026-04-03 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: net: usb: cdc_ncm: add ndpoffset to NDP16 nframes bounds check cdc_ncm_rx_verify_ndp16() validates that the NDP header and its DPE entries fit within the skb. The first check correctly accounts for ndpoffset: if ((ndpoffset + sizeof(struct usb_cdc_ncm_ndp16)) > skb_in->len) but the second check omits it: if ((sizeof(struct usb_cdc_ncm_ndp16) + ret * (sizeof(struct usb_cdc_ncm_dpe16))) > skb_in->len) This validates the DPE array size against the total skb length as if the NDP were at offset 0, rather than at ndpoffset. When the NDP is placed near the end of the NTB (large wNdpIndex), the DPE entries can extend past the skb data buffer even though the check passes. cdc_ncm_rx_fixup() then reads out-of-bounds memory when iterating the DPE array. Add ndpoffset to the nframes bounds check and use struct_size_t() to express the NDP-plus-DPE-array size more clearly.
CVE-2026-34872 2 Arm, Mbed-tls 3 Mbed Tls, Tf-psa-crypto, Mbedtls 2026-04-03 9.1 Critical
An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values (lack of contributory behavior). This is a problem for protocols that depend on contributory behavior (which is not the case for TLS). The attack can be carried by the peer, or depending on the protocol by an active network attacker (person in the middle).
CVE-2026-34545 1 Academysoftwarefoundation 1 Openexr 2026-04-03 8.8 High
OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From version 3.4.0 to before version 3.4.7, an attacker providing a crafted .exr file with HTJ2K compression and a channel width of 32768 can write controlled data beyond the output heap buffer in any application that decodes EXR images. The write primitive is 2 bytes per overflow iteration or 4 bytes (by another path), repeating for each additional pixel past the overflow point. In this context, a heap write overflow can lead to remote code execution on systems. This issue has been patched in version 3.4.7.
CVE-2026-34835 1 Rack 1 Rack 2026-04-03 4.8 Medium
Rack is a modular Ruby web server interface. From versions 3.0.0.beta1 to before 3.1.21, and 3.2.0 to before 3.2.6, Rack::Request parses the Host header using an AUTHORITY regular expression that accepts characters not permitted in RFC-compliant hostnames, including /, ?, #, and @. Because req.host returns the full parsed value, applications that validate hosts using naive prefix or suffix checks can be bypassed. This can lead to host header poisoning in applications that use req.host, req.url, or req.base_url for link generation, redirects, or origin validation. This issue has been patched in versions 3.1.21 and 3.2.6.
CVE-2026-5313 1 Nothings 1 Stb 2026-04-03 4.3 Medium
A vulnerability has been found in Nothings stb up to 2.30. This issue affects the function stbi__gif_load_next in the library stb_image.h of the component GIF Decoder. Such manipulation leads to denial of service. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A Business Logic vulnerability exists in SourceCodester Pharmacy Product Management System 1.0. The vulnerability is located in the add-sales.php file. The application fails to validate the "txtprice" and "txttotalcost" parameters, allowing attackers to submit negative values for sales transactions. This leads to incorrect financial calculations, corruption of sales reports, and potential financial loss.
CVE-2026-34519 1 Aio-libs 1 Aiohttp 2026-04-03 5.3 Medium
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.13.4, an attacker who controls the reason parameter when creating a Response may be able to inject extra headers or similar exploits. This issue has been patched in version 3.13.4.
CVE-2026-33762 2 Go-git, Go-git Project 2 Go-git, Go-git 2026-04-03 2.8 Low
go-git is an extensible git implementation library written in pure Go. Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.
CVE-2026-22569 1 Zscaler 1 Client Connector 2026-04-03 5.4 Medium
An incorrect startup configuration of affected versions of Zscaler Client Connector on Windows may cause a limited amount of traffic from being inspected under rare circumstances.
CVE-2026-23395 1 Linux 1 Linux Kernel 2026-04-02 8.8 High
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix accepting multiple L2CAP_ECRED_CONN_REQ Currently the code attempts to accept requests regardless of the command identifier which may cause multiple requests to be marked as pending (FLAG_DEFER_SETUP) which can cause more than L2CAP_ECRED_MAX_CID(5) to be allocated in l2cap_ecred_rsp_defer causing an overflow. The spec is quite clear that the same identifier shall not be used on subsequent requests: 'Within each signaling channel a different Identifier shall be used for each successive request or indication.' https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/Core-62/out/en/host/logical-link-control-and-adaptation-protocol-specification.html#UUID-32a25a06-4aa4-c6c7-77c5-dcfe3682355d So this attempts to check if there are any channels pending with the same identifier and rejects if any are found.
CVE-2026-23407 1 Linux 1 Linux Kernel 2026-04-02 7.8 High
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix missing bounds check on DEFAULT table in verify_dfa() The verify_dfa() function only checks DEFAULT_TABLE bounds when the state is not differentially encoded. When the verification loop traverses the differential encoding chain, it reads k = DEFAULT_TABLE[j] and uses k as an array index without validation. A malformed DFA with DEFAULT_TABLE[j] >= state_count, therefore, causes both out-of-bounds reads and writes.

CVE-2026-32877 1 Randombit 1 Botan 2026-04-02 8.2 High
Botan is a C++ cryptography library. From version 2.3.0 to before version 3.11.0, during SM2 decryption, the code that checked the authentication code value (C3) failed to check that the encoded value was of the expected length prior to comparison. An invalid ciphertext can cause a heap over-read of up to 31 bytes, resulting in a crash or potentially other undefined behavior. This issue has been patched in version 3.11.0.
CVE-2026-33977 1 Freerdp 1 Freerdp 2026-04-02 6.5 Medium
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, a malicious RDP server can crash the FreeRDP client by sending audio data in IMA ADPCM format with an invalid initial step index value (>= 89). The unvalidated step index is read directly from the network and used to index into a 89-entry lookup table, triggering a WINPR_ASSERT() failure and process abort via SIGABRT. This affects any FreeRDP client that has audio redirection (RDPSND) enabled, which is the default configuration. This issue has been patched in version 3.24.2.
