| CVE | Score | Severity | Package | Description | Published |
|---|---|---|---|---|---|
| CVE-2026-3446 |
5.3 (i)
| MEDIUM | python | When calling base64.b64decode() or related functions the decoding process would stop after encountering the first padded quad regardless of whether there was more information to be processed. This can lead to data being accepted which may be processed differently by other implementations. Use "validate=True" to enable stricter processing of base64 data. | 2026-04-10 |
| CVE-2026-39892 |
5.3 (i)
| MEDIUM | cryptography | cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7. | 2026-04-08 |
| CVE-2026-31790 |
5.6 (i)
| MEDIUM | openssl | Issue summary: Applications using RSASVE key encapsulation to establisha secret encryption key can send contents of an uninitialized memory buffer toa malicious peer.Impact summary: The uninitialized buffer might contain sensitive data from theprevious execution of the application process which leads to sensitive dataleakage to an attacker.RSA_public_encrypt() returns the number of bytes written on success and -1on error. The affected code tests only whether the return value is non-zero.As a result, if RSA encryption fails, encapsulation can still return success tothe caller, set the output lengths, and leave the caller to use the contents ofthe ciphertext buffer as if a valid KEM ciphertext had been produced.If applications use EVP_PKEY_encapsulate() with RSA/RSASVE on anattacker-supplied invalid RSA public key without first validating that key,then this may cause stale or uninitialized contents of the caller-providedciphertext buffer to be disclosed to the attacker in place of the KEMciphertext.As a workaround calling EVP_PKEY_public_check() orEVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate() will mitigatethe issue.The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.1 and 3.0 are affected by this issue. | 2026-04-07 |
| CVE-2026-28390 |
5.9 (i)
| MEDIUM | openssl | Issue summary: During processing of a crafted CMS EnvelopedData messagewith KeyTransportRecipientInfo a NULL pointer dereference can happen.Impact summary: Applications that process attacker-controlled CMS data maycrash before authentication or cryptographic operations occur resulting inDenial of Service.When a CMS EnvelopedData message that uses KeyTransportRecipientInfo withRSA-OAEP encryption is processed, the optional parameters field ofRSA-OAEP SourceFunc algorithm identifier is examined without checkingfor its presence. This results in a NULL pointer dereference if the fieldis missing.Applications and services that call CMS_decrypt() on untrusted input(e.g., S/MIME processing or CMS-based protocols) are vulnerable.The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by thisissue, as the affected code is outside the OpenSSL FIPS module boundary. | 2026-04-07 |
| CVE-2026-4292 |
2.7 (i)
| LOW | django | An issue was discovered in 6.0 before 6.0.4, 5.2 before 5.2.13, and 4.2 before 4.2.30.Admin changelist forms using `ModelAdmin.list_editable` incorrectly allowed newinstances to be created via forged `POST` data.Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.Django would like to thank Cantina for reporting this issue. | 2026-04-07 |
| CVE-2026-35177 |
4.1 (i)
| MEDIUM | vim | Vim is an open source, command line text editor. Prior to 9.2.0280, a path traversal bypass in Vim's zip.vim plugin allows overwriting of arbitrary files when opening specially crafted zip archives, circumventing the previous fix for CVE-2025-53906. This vulnerability is fixed in 9.2.0280. | 2026-04-06 |
| CVE-2026-5704 |
5.5 (i)
| MEDIUM | tar | A flaw was found in tar. A remote attacker could exploit this vulnerability by crafting a malicious archive, leading to hidden file injection with fully attacker-controlled content. This bypasses pre-extraction inspection mechanisms, potentially allowing an attacker to introduce malicious files onto a system without detection. | 2026-04-06 |
| CVE-2026-34982 |
8.2 (i)
| HIGH | vim | Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The `complete`, `guitabtooltip` and `printheader` options are missing the `P_MLE` flag, allowing a modeline to be executed. Additionally, the `mapset()` function lacks a `check_secure()` call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue. | 2026-04-06 |
| CVE-2026-5673 |
5.6 (i)
| MEDIUM | libtheora | A flaw was found in libtheora. This heap-based out-of-bounds read vulnerability exists within the AVI (Audio Video Interleave) parser, specifically in the avi_parse_input_file() function. A local attacker could exploit this by tricking a user into opening a specially crafted AVI file containing a truncated header sub-chunk. This could lead to a denial-of-service (application crash) or potentially leak sensitive information from the heap. | 2026-04-06 |
| CVE-2026-34933 |
5.5 (i)
| MEDIUM | avahi | Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. Prior to version 0.9-rc4, any unprivileged local user can crash avahi-daemon by sending a single D-Bus method call with conflicting publish flags. This issue has been patched in version 0.9-rc4. | 2026-04-03 |
